How to use this tool

Generate and copy

Length is preset to 16. Keep Characters mode selected, choose which character sets to include, then click Copy. Use Regenerate for a new password. Generation stays in your browser with crypto.getRandomValues. Nothing is uploaded.

When 16 characters makes sense

Sixteen characters is a strong default for banking, email, and work accounts. A random 16-character password with a full character mix is much harder to guess than a short password. Store it in a password manager so you do not need to memorize it.

Spaces, symbols, and passphrases

Enable Symbols for special characters and Spaces if the site allows whitespace (spaces count toward the 16-character total). Exclude ambiguous removes lookalikes like 0, O, l, 1, and I. Switch to Words mode for a memorable passphrase from the EFF large wordlist.
