Password Generator
Generate strong random passwords or memorable passphrases, with a real entropy estimate. Never sent anywhere.
Options
Excludes l, I, 1, O, 0 and similar pairs.
Alphabet size: 86 characters.
About the password generator
Build a password from the character classes you want, at any length from 8 to 128, with options to avoid look-alike characters such as l, 1, I and O. Or switch to passphrase mode for several random words joined by a separator, which is far easier to type and remember at the same strength. Strength is reported as actual bits of entropy with an estimated time to crack, and generation uses the platform cryptographic random source locally.
This tool runs entirely in your browser. Nothing you type is uploaded, and it keeps working with no connection at all — including as an installed app.
