Create strong, unguessable passwords using your browser's cryptographic random number generator. Tune the length and character sets, watch the entropy update live, and copy the result. Nothing is ever transmitted or stored.
…Generated locally with your browser's cryptographic RNG. Nothing is sent to a server, logged, or stored.
A long random password is only useful if you never have to remember or reuse it. Pair this generator with a reputable password manager so every account gets a unique credential, and enable multi-factor authentication everywhere it is offered. For length, aim for 16 characters or more; each extra character multiplies the effort an attacker needs. Test any candidate in our password strength analyzer or talk to our team about enterprise credential policy.
Yes. The generator uses crypto.getRandomValues, the browser's cryptographically secure random number generator, with rejection sampling to avoid modulo bias. It does not use Math.random, which is not safe for secrets.
No. Generation happens entirely in your browser. The password is never transmitted over the network, logged, or stored. You can generate offline to confirm.
For most accounts, 16–20 random characters is strong. For high-value accounts, go longer. Because these passwords are random, length is the main lever for strength — the entropy readout shows the effect of each change.
Never reuse passwords across accounts. Generate a unique password for each service and store them in a password manager so a breach of one site cannot compromise the others.
