Cryptographically random strong passwords, ambiguous-char filter

Privacy: this tool runs entirely in your browser — files are never uploaded, and data is gone when you close the page.

How to use

  1. Drag the slider to pick a length (6–64).
  2. Toggle character types; optionally exclude ambiguous chars like 0O1lI.

FAQ

Are the passwords secure?

Yes. They use OS-level cryptographic randomness and never touch any server.

What if I forget it?

Save it to a password manager immediately — nothing is stored or recoverable here.

How long should it be?

12–16 characters suit most sites; use 16+ with two-factor auth for critical accounts.

About this Password Generator

Passwords come from the browser's crypto.getRandomValues — a cryptographic random source, not a predictable algorithm — and generation is fully offline. The strength readout is entropy-based: 60+ bits resists brute force well; use 16+ characters with 2FA for critical accounts.
