Passwords are calculated, not stored.
no vault. no cloud. no memory.

How It Works
01
1. Enter
Provide your Secret Key, the site name, and your account email.
02
2. Calculate
PassTerm runs PBKDF2 hash iterations mathematically.
03
3. Done
Your unique password is ready. Copy it and you're good to go.
Security by Design
No Vault
Passwords are never saved anywhere. There is no database to hack.
Fully Offline
Works completely offline. No internet connection is ever required.
Deterministic
Same inputs (site, account, secret key) always yield the same strong password.
PBKDF2 + HMAC-SHA256
Uses industry-standard cryptography with 100,000 iterations.
Cross-Platform
Available on Android and Windows with identical results.
Terminal UI
Minimalist, distraction-free interface designed for power users.
Q&A
[ what is passterm? ]
PassTerm is a deterministic password generator. It calculates passwords from your inputs — it never stores them.
[ what is a secret key? ]
Your master password. It's the seed for all generated passwords. Choose a strong one and never forget it.
[ is it safe? ]
Extremely. No internet connection required. No data leaves your device. No password database to hack. Open source algorithm.
[ what if i forget my secret key? ]
All passwords generated with that key are lost. There is no recovery method. This is by design — no backdoors.
[ how is this different from a password manager? ]
Password managers save your passwords in an encrypted vault, which can be leaked or hacked. PassTerm doesn't save anything; it calculates the password on the fly when you need it.
Security Guarantees
What PassTerm Guarantees
- No data collection, telemetry, or analytics.
- No network requests. Everything happens on your CPU.
- The algorithm is predictable and consistent across platforms.
What It Cannot Guarantee
- Protection against malware or keyloggers on your device.
- Recovering passwords if you forget your Secret Key.
- Clipboard snooping by other apps (though we auto-clear it).
