Password & Passphrase Generator
MAG212 CYBER · Tools
Password & passphrase generator.
Create strong random passwords or easy-to-remember passphrases using your device’s cryptographically secure random number generator. Nothing is sent or stored.
Generate
Uses crypto.getRandomValues() with rejection sampling, so every character or word is equally likely. Passphrases use the EFF large wordlist (7,776 words, CC BY 3.0) — about 12.9 bits of entropy per word. Check any password with the password strength & breach checker.
Password or passphrase?
| Use | Best choice | Why |
|---|---|---|
| Stored in a password manager | Random password, 20+ characters | Maximum strength; you never type it. |
| Password manager master password, computer login | Passphrase, 5–6 words | About 65–78 bits of entropy and memorable. |
| Wi-Fi network (WPA2/WPA3) | Passphrase, 5+ words | Easy to read out to guests; resists offline cracking of captured handshakes. |
| Network device local account | Random password, 20+ characters | Store it in a vault; prefer TACACS+/RADIUS for daily logins. |
