Deterministic Credentials Generator: Reproducible from a Seed
Deterministic credentials generate always the same output from a seed (password + service ID). Advantage: you don't need to store credentials anywhere — you can 'derive' them any time from your master seed. Concept popularized by tools like Master Password (Maarten Billemont).
Our generator uses PBKDF2 with 100,000+ iterations and SHA-256 to derive strong credentials from your master password. Each service generates a unique credential — if one leaks, the others are safe.
IMPORTANT: if you forget the master seed, you lose ALL credentials (there's no backup). Use with an extremely secure master password and consider having a written backup in a safe.
How does it work?
- 1Enter your master seed
A strong password that you'll use forever. Ideally 20+ characters, memorable but unpredictable.
- 2Enter the service name
Ex: 'gmail', 'twitter', 'my-bank-2026'. Case-sensitive.
- 3Get the credential
The deterministic result appears. Adjust length and character type as needed.
Frequently Asked Questions
A manager stores encrypted passwords (Bitwarden, 1Password). A deterministic generator DERIVES them from a seed — no need to sync between devices. Trade-off: harder to rotate a specific password (you'd have to change the service ID).
You lose access to ALL derived credentials. There's no recovery — that's the trade-off for not depending on a service. Have a written backup in a physical safe, or use hybrid systems (deterministic + password manager).
As long as your master seed is strong (>80 bits entropy) and derivation uses adequate iterations (100k+), yes. But if the master leaks, ALL derivations are compromised. That's why we recommend using with an incorruptible password.
