Password Generator
Free strong password generator with custom length and character set controls. Computed in your browser with no upload, built for throwaway accounts.
How it works
- Longer passwords mean exponentially longer cracking times.
- Mixing cases, digits, and symbols raises entropy.
- Randomness comes from crypto.getRandomValues. Built into your browser.
About this tool
Why use a free password generator
When you create temporary emails, trial accounts, or QA identities, reusing your primary password is risky. This tool generates strong random passwords with the Web Crypto API entirely in your browser — nothing is uploaded or stored on our servers.
How to use it
Pick a length (16+ is a solid default), enable lowercase, uppercase, digits, and symbols, click generate, then copy into the signup form. Use a unique password per site.
Pair with temporary email
Create a disposable address on Freetempmail, generate a strong password here, complete signup, then discard the inbox when finished. Your primary mailbox and primary password stay out of the blast radius. See signup without spam and developer testing.
Security notes
Generation is local-only. Do not paste generated passwords into public channels. For banks, government, and healthcare, use a real password manager and a permanent recovery email — not a disposable inbox.
