Password Generator

A password generator creates random passwords that are hard to guess, unlike the names, dates and patterns people choose themselves. Reused and predictable passwords are behind most account takeovers, so a fresh random password for each site is one of the simplest protections there is.

This generator lets you choose the length and which characters to use, avoids confusing look-alikes if you like, and creates up to 20 passwords at once with a strength meter based on entropy. It runs entirely in your browser using cryptographic randomness, and only your settings, never the passwords, are kept in the page address.

Strength comes from randomness and length. Entropy, in bits, is length × log₂(number of possible characters): 16 characters from all four sets, 87 possible characters, is about 103 bits, far beyond what can be guessed. Each extra character adds more strength than any special-character rule.

Passwords here use the browser's cryptographic random generator, with at least one character from every set you tick, and are never put in the page address, sent or stored. Use a different password for every site and keep them in a password manager.
