Password Generator Documentation

Create strong random passwords with adjustable length and symbol support.

Select Generate password to create a value locally with Web Crypto; the initial length is 18 characters. You can choose 8-64 characters and include symbols. Rejection sampling selects characters uniformly. A diversity heuristic and generation-entropy estimate describe the current output without promising a crack time. The separate 35-word passphrase mode is a low-entropy demonstration, not an account-credential recommendation.

• Generate random text for a development account under a compatible password policy.
• Compare alphabet size and length in a generation-entropy estimate.
• Demonstrate why a small word list gives low-entropy passphrases.

Input

Text, files, or values entered in the browser, depending on the tool.

Output

A result shown in the browser that can be reviewed or copied where supported.

• Independent uniform selection does not guarantee at least one character from every class; check the destination's password rules.
• The passphrase dictionary has only 35 words: four independent words provide about 20.5 bits, not adequate account security.
• Length/diversity labels are heuristics, not breach checks or security guarantees. Browser extensions and clipboard history can expose copied values.
