About this tool
A strong password is long, random and unique. This generator uses the Web Crypto API — specifically crypto.getRandomValues — to produce passwords that are cryptographically random, not pseudorandom like Math.random().
How to use it
- Choose a length (16 characters or more is recommended).
- Select which character sets to include.
- Click Generate.
- Copy the password and store it in a password manager.
Common problems
- The generated password is rejected by a site.
- Some sites ban specific symbols. Uncheck 'Symbols' and re-generate, or try a shorter subset by editing the generated password manually.
