Password Generator

Strong random passwords with custom length and character sets.

How the generator works

Passwords are generated locally in your browser using the cryptographically secure Web Crypto API — nothing is sent to any server. Choose the length and which character sets to include, then copy with one click.

What makes a password strong

Length beats complexity: a 16-character random password is vastly stronger than an 8-character one with symbols. Use a unique password per site and store them in a password manager rather than reusing variants.

Frequently asked questions

How long should my password be?

At least 12–16 characters for important accounts. Every extra character multiplies the cracking effort.

Is it safe to generate passwords online?

Here, yes — generation uses your browser's secure random number generator and the password never leaves your device.
