16 characters is a common sweet spot — long enough for strong entropy with all character types, short enough to fit most system limits. This page defaults to exactly that length.
Create several passwords at once using the settings above — useful for provisioning multiple accounts.
Type any password to score it instantly. This runs entirely in your browser — nothing is sent anywhere, logged, or stored.
Most modern systems accept 16 characters comfortably, but a few older ones cap password length lower — check first if you're unsure.
At 16 characters, using all four character types gets you well past 100 bits of entropy — a strong result.
16 is a strong default, but you can move the length slider up or down depending on the specific system's requirements.
For most accounts, yes — with all character types enabled, 16 characters exceeds 100 bits of entropy, well into strong territory.
It balances strong entropy against the character limits still enforced by some older systems, making it a safe practical default.
Consider going longer — 20-24 characters or more — for a master password specifically, since it protects everything else.
