About our security tools

The password generator uses crypto.getRandomValues, the same secure random source browsers use for encryption, and the password strength tester estimates entropy and crack time without ever transmitting what you type.

For private notes, the steganography studio can hide AES-256 encrypted messages inside invisible characters or image pixels.

Frequently asked questions

How long should my password be?

Use at least 14–16 random characters, or a passphrase of five or more random words. Length adds far more strength than swapping letters for symbols.

Is it safe to test my real password here?

The checker runs entirely offline in your browser and never sends what you type. That said, it's good practice to test a similar password rather than your exact one.

Should I use a password manager?

Yes. A password manager lets you use a unique, randomly generated password for every site, which is the single most effective protection against breaches.
