Why it is safe

Cryptographic randomness

Characters are chosen with crypto.getRandomValues — no predictable patterns and no bias.

Browser only

The password is created on your device. It is never sent to a server and never stored.

Guaranteed mix

The password always contains at least one character from every selected type.

FAQ

Are passwords generated on a server?

No. The password is generated right in your browser with a cryptographic random number generator. It is never sent anywhere and never stored.

What makes a password strong?

Length and uniqueness. For most services 16–20 characters with mixed case, digits and symbols is plenty. The key is never reusing one password across sites.

How do I remember such a password?

Don't — store it in a password manager, which creates and fills unique passwords for you automatically.

Is it free?

Yes, completely free and no sign-up.
