About the Strong Password Generator
Create random passwords using your browser’s cryptographic random number generator. Choose the length and character types and see an entropy-based strength estimate. Nothing is sent or stored.
How to use it
- Set the length and the character types.
- Press Generate.
- Copy the password into your password manager.
Frequently asked questions
How long should a password be?
At least 14 characters for ordinary accounts and 20 or more for important ones. Length matters more than clever substitutions.
Is it safe to generate passwords online?
This one runs entirely in your browser using crypto.getRandomValues, and the password is never transmitted. Store it in a password manager.
