Password generator
Create a long, random and unique password. It is generated in your browser and is not sent or stored.
Levels are configuration shortcuts. You can adjust length and characters at any time.
Features
Cryptographic randomness
Uses crypto.getRandomValues() and rejection sampling.
Password or passphrase
Control character groups or generate a local multi-word passphrase with cryptographic randomness.
Not stored
The password exists only in the page open in your browser.
How passwords are generated
The browser provides cryptographically strong random numbers through Web Crypto. The tool uses those values to select characters and avoids a simple modulo reduction when that would introduce bias.
What the levels mean
Easy, Normal, Hard and Very hard are shortcuts for choosing a configuration without starting from scratch. They mainly change length and character variety. You can then adjust any option to match what the service accepts.
Frequently asked questions
Do you store the password?
No. The password is generated in your browser and is not sent to Rusadix Tools infrastructure or stored in an account.
What is the minimum length?
This version allows between 12 and 128 characters. Presets start at 16 so the quick options do not offer an unnecessarily short password.
