About this tool
Set a length and choose whether to include numbers and symbols, then click Randomise. Generation uses your browser’s cryptographically secure random number generator, with unbiased character selection (rejection sampling, not a naive modulo) so every allowed character is equally likely.
Frequently asked questions
- How random is this?
- It uses the Web Crypto API's crypto.getRandomValues() — a cryptographically secure random source, the same one browsers use for other security-sensitive features — not Math.random().
- What characters are always included?
- Uppercase and lowercase letters are always included. Numbers and symbols are optional, toggled independently.
- Is my generated password sent to your servers?
- No. Every password is generated entirely in your browser and never transmitted or logged anywhere.
