Test any password:
Password Generator — Web Edition
Click 🔑 Generate Password to instantly create a new password using the crypto.getRandomValues() API — the same engine browsers use for TLS. No Math.random() shortcuts here.
Use the Length slider or type a value between 8 and 64. Toggle a-z, A-Z, 0-9 and symbols to shape your character pool. Check "Avoid ambiguous" to skip confusing chars like 0, O, 1, l, I.
Enable Passphrase Mode for Diceware-style phrases. Choose 3–8 words and pick your separator (dash, underscore, or space). Great for memorable yet strong passwords.
The Presets dropdown lets you jump straight to common configs: a strong 16-char password, an ultra-secure 24-char, a 4-word or 6-word passphrase. One click, instant results.
Every password you generate is saved in the Generation History list. Click 📋 on any row to copy it, or × to remove it. Export the full list as a .txt file for safekeeping.
Paste any existing password into the Test any password field and click Analyze. The terminal in the right panel will score it and show exactly what's weak or strong.
CrunchyPass uses the browser's Web Crypto API for true cryptographic randomness. There are no servers, no logs, no network requests. Close the tab and the history is gone — by design.
