Tool

# Password generator

Create a strong, random password right in your browser. Nothing is sent anywhere: the generator runs entirely on your machine, built by someone who cracks passwords for a living.

••••••••••••••••••••

## How the generator works

The password is created by your browser’s built-in cryptographic random generator (the Web Crypto API), directly on your machine. Nothing is sent to any server, nothing is stored, and nothing is logged. Feel free to turn off your internet before pressing the button, the generator works anyway.

The crack-time estimate assumes the worst case: an attacker with serious hardware guessing around a trillion passwords per second against a leaked password database. Length always beats “complex”: every extra character multiplies the work many times over.

## Tips from an ethical hacker

- Use a [password manager](https://danielchristensen.no/en/glossary#passordbehandler) so you don’t have to remember anything at all. One unique password per service matters more than one “perfect” password.
- Never reuse passwords. When one service leaks, criminals try that same password everywhere else.
- Turn on [two-factor authentication](https://danielchristensen.no/en/glossary#totrinnsverifisering) on your email first. It stops most account takeovers, even when the password leaks.
- Length beats everything. A long password without symbols is stronger than a short one with all the tricks.
