Random 15 Key Password Generator

  1. May 28, 2018  I get tired of thinking up unique and strong passwords. So anymore, for the most part, I don’t do it. I will use random generated passwords, then save them into an Azure KeyVault. It is a good way to use strong passwords that are practically impossible to remember but then keep them usable and within.
  2. This is the 15 character version, see also the 10 char. And extra-strong 20 character versions. For websites that ask for 'letter 3 and letter 7 from your password' the password is counted out at the bottom. Click on the password to make this appear. This is the only version of the password generator with that feature.
  3. Making your passwords different for each website or app also helps defend against hacking. This password generator tool runs locally on your Windows, Mac or Linux computer, as well as your iOS or Android device. The passwords you generate are never sent across the web. The best password tips from the pros.

Details about the built-in password generator of KeePass.



Generation Based on Character Sets

This password generation method is the recommended way to generate random passwords. Other methods (pattern-based generation, ..) should only be used if passwords must follow special rules or fulfill certain conditions.

Generation based on a character set is very simple. You simply let KeePass know which characters can be used (e.g. upper-case letters, digits, ..) and KeePass will randomly pick characters out of the set.

Defining a character set:
The character set can be defined directly in the password generator window. For convenience, KeePass offers adding commonly used ranges of characters to the set. This is done by ticking the appropriate check box. Additionally to these predefined character ranges, you can specify characters manually: all characters that you enter in the 'Also include the following characters' text box will be directly added to the character set.

The characters that you enter in the 'Also include the following characters' text box are included in the character set from which the password generator randomly chooses characters from. This means that these additional characters are allowed to appear in the generated passwords, but they are not forced to. If you want to force that some characters appear in the generated passwords, you have to use the pattern-based generation.

Character sets are sets:
In mathematical terms, character sets are sets, not vectors. This means that characters cannot be added twice to the set. Either a character is in the set or it is not.

For example, if you enter 'AAAAB' into the additional characters box, this is exactly the same set as 'AB'. 'A' will not be 4 times as likely as 'B'! If you need to follow rules like 'character A is more likely than B', you must use pattern-based generation + permuting password characters.

KeePass will 'optimize' your character set by removing all duplicate characters. If you'd enter the character set 'AAAAB' into the additional characters box, close and reopen the password generator, it'll show the shorter character set 'AB'. Similarly, if you tick the Digits check box and enter '3' into the additional box, the '3' will be ignored because it is already included in the Digits character range.

Supported characters:
All Unicode characters in the ranges [U+0001, U+D7FF] and [U+E000, U+FFFF] except { U+0009 / 't', U+000A / 'n', U+000D / 'r' } are supported. Characters in the range [U+010000, U+10FFFF] (which need to be encoded in UTF-16 using surrogate pairs from [0xD800, 0xDFFF]) are not supported. Subsequent processing of passwords may have further limitations (for example, the character U+FFFF is forbidden in XML/KDBX files and will be replaced or removed).


Generation Based on Patterns

The password generator can create passwords using patterns. A pattern is a string defining the layout of the new password. The following placeholders are supported:

PlaceholderTypeCharacter Set
aLower-Case Alphanumericabcdefghijklmnopqrstuvwxyz 0123456789
AMixed-Case AlphanumericABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 0123456789

Escape (Fixed Char)Use following character as is.
{n}Escape (Repeat)Repeat the previous placeholder n times.
[..]Custom Char SetDefine a custom character set.

The placeholder is special: it's an escape character. The next character that follows the is written directly into the generated password. If you want a in your password at a specific place, you have to write .

Using the {n} code you can define how many times the previous placeholder should occur. The { } operator duplicates placeholders, not generated characters. Examples:
» d{4} is equivalent to dddd,
» dH{4}a is equivalent to dHHHHa and
» Hda{1}dH is equivalent to HdadH.

The [..] notation can be used to define a custom character set, from which the password generator will pick one character randomly. All characters between the '[' and ']' brackets follow the same rules as the placeholders above. The '^' character removes the next placeholders from the character set. Examples:
» [dp] generates exactly 1 random character out of the set digits + punctuation,
» [dm@^3]{5} generates 5 characters out of the set '012456789m@',
» [u_][u_] generates 2 characters out of the set upper-case + '_'.

More examples:

ddddd
Generates for example: 41922, 12733, 43960, 07660, 12390, 74680, ..

Hex: HHHHHH
Generates for example: 'Hex: 13567A', 'Hex: A6B99D', 'Hex: 02243C', ..

Generating Passwords that Follow Rules

Below are a few examples how the pattern generation feature can be used to generate passwords that follow certain rules.

Important! For all of the following examples you must enable the 'Randomly permute characters of password' option!

RulePattern
Must consist of 2 upper-case letters, 2 lower-case letters and 2 digits.uulldd
Must consist of 9 digits and 1 letter.d{9}L
Must consist of 10 alphanumeric characters, where at least 1 is a letter and at least 1 is a digit.LdA{8}
Must consist of 10 alphanumeric characters, where at least 2 are upper-case letters and at least 2 are lower-case letters.uullA{6}
Must consist of 9 characters of the set 'ABCDEF' and an '@' symbol.@[ABCDEF]{9}

Security-Reducing Options

The password generator supports several options like 'Each character must occur at most once', 'Exclude look-alike characters', and a field to explicitly specify characters that should not appear in generated passwords.

These options are reducing the security of generated passwords. You should only enable them if you are forced to follow such rules by the website/application, for which you are generating the password.

The options can be found in the 'Advanced' dialog / tab page.

If you enable a security-reducing option, the 'Advanced' button
in the password generator window is shown in red.

If you enable a security-reducing option, an exclamation mark (!)
is appended to the 'Advanced' tab.

Creating and Using Password Generator Profiles

Password generator options (character set, length, pattern, ..) can be saved as password generator profiles.

Creating/modifying a profile:

  1. Open the Password Generator window.
  2. Specify all options of the new profile.
  3. Click the 'Save as Profile' button.
  4. Enter the name of the new profile, or select an existing profile name from the drop-down list to overwrite it. Close the dialog with OK.
  5. If you want to immediately create a password using the new profile, click OK/Accept. Otherwise click Cancel/Close (the profile is not lost; profile management is independent of password generation).

Using a profile:
To use a profile, simply select it from the drop-down profiles list in the password generator window. All settings of this profile will be restored accordingly. Angry birds star wars activation key generator reviews.

Meta-profile 'Derive from previous password':
When this meta-profile is selected, a password is generated based on a character set derived from the previous password. The new password has the same length as the old one, and every character of the old password turns on the character subset that contains this character. For example, if the old password contains the letter 'R', then the character set used for generating the new password contains the range 'A' to 'Z'.
Warning! This meta-profile should not be used blindly (i.e. without reviewing the used character set). The new password does not necessarily contain at least one character from each character subset (see 'Generation Based on Character Sets'), thus blindly generating new passwords with this meta-profile can result in a quality degradation of the effectively used profile.


Configuring Settings of Automatically Generated Passwords for New Entries

Password Random Generator

When you create a new entry, KeePass will automatically generate a random password for it. The properties of these generated passwords can be configured in the password generator dialog.

To configure, specify the options of your choice and overwrite the '(Automatically generated passwords for new entries)' profile (see section above).

Disabling automatically generated passwords:
To disable automatically generated passwords for new entries, select 'Generate using character set' and specify 0 as password length. Overwrite the appropriate profile (see above).

What makes these perfect and safe?
Every one is completely random (maximum entropy) without any pattern, and the cryptographically-strong pseudo random number generator we use guarantees that no similar strings will ever be produced again.

Also, because this page will only allow itself to be displayed over a snoop-proof and proxy-proof high-security SSL connection, and it is marked as having expired back in 1999, this page which was custom generated just now for you will not be cached or visible to anyone else.

Therefore, these password strings are just for you. No one else can ever see them or get them. You may safely take these strings as they are, or use chunks from several to build your own if you prefer, or do whatever you want with them. Each set displayed are totally, uniquely yours — forever.

The 'Application Notes' section below discusses various aspects of using these random passwords for locking down wireless WEP and WPA networks, for use as VPN shared secrets, as well as for other purposes.

The 'Techie Details' section at the end describes exactly how these super-strong maximum-entropy passwords are generated (to satisfy the uber-geek inside you).

Application Notes:

A note about 'random' and 'pseudo-random' terminology:
Throughout this page I use the shorthand term 'random' instead of the longer but more precise term 'pseudo-random'. I use the output of this page — myself — for any purpose, without hesitation, any time I need a chunk of randomness because there is no better place to find anything more trusted, random and safe. The 'pseudo-randomness' of these numbers does not make them any less good.

There are ways to generate absolutely random numbers, but computer algorithms cannot be used for that, since, by definition, no deterministic mathematical algorithm can generate a random result. Electrical and mechanical noise found in chaotic physical systems can be tapped and used as a source of true randomness, but this is much more than is needed for our purposes here. High quality algorithms are sufficient.

The deterministic binary noise generated by my server, which is then converted into various displayable formats, is derived from the highest quality mathematical pseudo-random algorithms known. In other words, these password strings are as random as anything non-random can be.

This page's password 'raw material':
The raw password material is provided in several formats to support its use in many different applications. Each of the password strings on the page is generated independently of every other, based upon its own unique pseudo-random binary data. So there is no underlying similarity in the data among the various format passwords.

64 hex characters = 256 binary bits:

3807FFACB7A0EFC988534D593AB9ECBED42F09CA249D20EDADBA055CEF32AA9D
Each of the 64 hexadecimal characters encodes 4 bits of binary data, so the entire 64 characters is equivalent to 256 binary bits — which is the actual binary key length used by the WiFi WPA pre-shared key (PSK). Some WPA-PSK user interfaces (such as the one in Windows XP) allows the 256-bit WPA pre-shared key to be directly provided as 64 hexadecimal characters. This is a precise means for supplying the WPA keying material, but it is ONLY useful if ALL of the devices in a WPA-protected WiFi network allow the 256-bit keying material to be specified as raw hex. If any device did not support this mode of specification (and most do not) it would not be able to join the network.

Using fewer hex characters for WEP encryption:
If some of your WiFi network cannot support the newer and much stronger (effectively unbreakable when used with maximum-entropy keys like these) WPA encryption system, you'll be forced either to run two WiFi networks in parallel (which is totally feasible — one super-secure and one at lower security) or to downgrade your entire network to weaker WEP encryption. Still, ANY encryption is better than no encryption.

WEP key strength (key length) is sometimes confusing because, although there are only two widely accepted standard lengths, 40-bit and 104-bit, those lengths are sometimes confused by adding the 24-bit IV (initialization vector) counter to the length, resulting in 64-bit and 128-bit total key lengths.

However, the user only ever specifies a key of either 40 or 104 binary bits. Since WEP keys should always be specified in their hexadecimal form to guarantee device interaction, and since each hex digit represents 4 binary bits of the key, 40 and 104 bit keys are represented by 10 and 26 hex digits respectively. So you may simply snip off whatever length of random hex characters you require for your system's WEP key.

Note that if all of your equipment supports the use of the new longer 256/232 bit WEP keys, you would use 232/4 or 58 hexadecimal characters for your pre-shared key.

The more 'standard' means for specifying the 256-bits of WPA keying material is for the user to specify a string of up to 63 printable ASCII characters. This string is then 'hashed' along with the network's SSID designation to form a cryptographically strong 256-bit result which is then used by all devices within the WPA-secured WiFi network. (The ASCII character set was updated to remove SPACE characters since a number of WPA devices were not handling spaces as they should.)


The 63 alphanumeric-only character subset:

If some device was not following the WiFi Alliance WPA specification by not hashing the entire printable ASCII character set correctly, it would end up with a different 256-bit hash result than devices that correctly obeyed the specification. It would then be unable to connect to any network that uses the full range of printable ASCII characters.

Since we have heard unconfirmed anecdotal reports of such non-compliant WPA devices (and since you might have one), this page also offers 'junior' WPA password strings using only the 'easy' ASCII characters which even any non-fully-specification-compliant device would have to be able to properly handle. If you find that using the full random ASCII character set within your WPA-PSK protected WiFi network causes one of your devices to be unable to connect to your WPA protected access point, you can downgrade your WPA network to 'easy ASCII' by using one of these easy keys.

And don't worry for a moment about using an easy ASCII key. If you still use a full-length 63 character key, your entire network will still be EXTREMELY secure. And PLEASE drop us a line to let us know that you have such a device and what it is!


Shorter pieces are random too:
A beneficial property of these maximum entropy pseudo-random passwords is their lack of 'inter-symbol memory.' This means that in a string of symbols, any of the possible password symbols is equally likely to occur next. This is important if your application requires you to use shorter password strings. Any 'sub-string' of symbols will be just as random and high quality as any other.


When does size matter?
The use of these maximum-entropy passwords minimizes (essentially zeroes) the likelihood of successful 'dictionary attacks' since these passwords won't appear in any dictionary. So you should always try to use passwords like these.

When these passwords are used to generate pre-shared keys for protecting WPA WiFi and VPN networks, the only known attack is the use of 'brute force' — trying every possible password combination. Brute force attackers hope that the network's designer (you) were lazy and used a shorter password for 'convenience'. So they start by trying all one-character passwords, then two-character, then three and so on, working their way up toward longer random passwords.

Since the passwords used to generate pre-shared keys are configured into the network only once, and do not need to be entered by their users every time, the best practice is to use the longest possible password and never worry about your password security again.

Note that while this 'the longer the better' rule of thumb is always true, long passwords won't protect legacy WEP-protected networks due to well known and readily exploited weaknesses in the WEP keying system and its misuse of WEP's RC4 encryption. With WEP protection, even a highly random maximum-entropy key can be cracked in a few hours. (Listen to Security Now! episode #11 for the full story on cracking WEP security.)

The Techie Details:
Since its introduction, this Perfect Passwords page has generated a great deal of interest. A number of people have wished to duplicate this page on their own sites, and others have wanted to know exactly how these super-strong and guaranteed-to-be-unique never repeating passwords are generated. The following diagram and discussion provides full disclosure of the pseudo-random number generating algorithm I employed to create the passwords on this page:



While the diagram above might at first seem a bit confusing, it is a common and well understood configuration of standard cryptographic elements. A succinct written description of the algorithm would read: 'Rijndael (AES) block encryption of never-repeating counter values in CBC mode.'
CBC stands for 'Cipher Block Chaining' and, as I describe in detail in the second half of Security Now! Episode #107, CBC provides necessary security in situations where some repetition or predictability of the 'plaintext' message is present. Since the 'plaintext' in this instance is a large 128-bit steadily-increasing (monotonic) counter value (which gives us our guaranteed never-to-repeat property, but is also extremely predictable) we need to scramble it so that the value being encrypted cannot be predicted. This is what 'CBC' does: As the diagram above shows, the output from the previous encryption operation is 'fed back' and XOR-mixed with the incrementing counter value. This prevents the possibility of determining the secret key by analysing successive counter encryption results.
One last detail: Since there is no 'output from the previous encryption' to be used during the encryption of the first block, the switch shown in the diagram above is used to supply a 128-bit 'Initialization Vector' (which is just 128-bits of secret random data) for the XOR-mixing of the first counter value. Thus, the first encryption is performed on a mixture of the 128-bit counter and the 'Initialization Vector' value, and subsequent encryptions are performed on the mixture of the incrementing counter and the previous encrypted result.
The result of the combination of the 256-bit Rijndael/AES secret key, the unknowable (therefore secret) present value of the 128-bit monotonically incrementing counter, and the 128-bit secret Initialization Vector (IV) is 512-bits of secret data providing extremely high security for the generation of this page's 'perfect passwords'. No one is going to figure out what passwords you have just received.
How much security do 512 binary bits provide? Well, 2^512 (2 raised to the power of 512) is the total number of possible combinations of those 512 binary bits — every single bit of which actively participates in determining this page's successive password sequence. 2^512 is approximately equal to: 1.34078079 x 10^154, which is this rather amazing number:
13, 407, 807, 929, 942, 597, 099, 574, 024, 998, 205,
846, 127, 479, 365, 820, 592, 393, 377, 723, 561, 443,
721, 764, 030, 073, 546, 976, 801, 874, 298, 166, 903,
427, 690, 031, 858, 186, 486, 050, 853, 753, 882, 811,
946, 569, 946, 433, 649, 060, 084, 096
As far as the crypto experts know, the only workable 'attack' on the Rijndael (AES) cipher lying at the heart of this system is 'brute force' — which means trying each one of those many combinations of 512 bits. In other words, the passwords being generated by GRC's server and presented for your exclusive use on this page, are safe.
