Password generator

How it works

Reusing the same password (or slight variants) across several accounts is one of the main causes of cascading breaches: if a single service suffers a data leak, every account using the same password becomes vulnerable. This tool generates a list of independent random passwords in one click, based on the length and character types you choose (uppercase, numbers, symbols), so that each account — email, bank, social network, work service — has its own unique, strong password, to then be stored in a password manager.

Are these passwords really random and safe?

Yes. Generation relies on the browser's secure cryptographic API, executed locally on your device via WebAssembly: no generated password is transmitted to a server or stored anywhere other than in your browser for the duration of the session.

What password length is recommended in 2026?

With the steady increase in computing power available for brute-force attacks, a length of at least 16 characters combining uppercase, lowercase, numbers and symbols is now recommended for sensitive accounts (main email, password manager, bank accounts), compared to the 12 characters generally advised a few years ago.

Privacy: generation happens entirely in your browser via WebAssembly — your passwords are never sent to a server.
