Randomness You Can Trust

Most password generators are weak because their randomness is weak. This password generator uses the browser's cryptographically secure random source and lets you choose length and character classes for any site's rules.

Choosing the Options

Longer beats complicated: 16 characters of lowercase-plus-digits outperforms 8 characters of symbol soup. Enable every class the site allows, exclude ambiguous characters if you will type the password by hand, and check the entropy readout — it should sit comfortably above 80 bits.

The Full Picture

The generated password's entropy and strength are computed live, so you can see exactly what your settings buy you. Copy it into your password manager and never into a chat — the whole point is that it appears nowhere except where you store it.
