The password manager that can't betray you.
OneLocked encrypts everything on your device before syncing. We never receive your master password or decrypted data, so the product’s protection model is structural instead of aspirational.
My Vault
A vault layout built to keep passwords, notes, cards, and identities organized without looking utilitarian.
Decryption stays on your device, which keeps the server outside the trust boundary for your vault contents.
Three steps to total security.
No theatrics, just a clearer protection flow from local key derivation to encrypted sync across devices.
Create your vault
Choose a strong master password and derive your encryption keys locally with PBKDF2 at 600,000 iterations.
Everything encrypts before sync
Passwords, cards, notes, and identities are protected on your device before ciphertext moves through the platform.
Access it anywhere
Your encrypted vault stays consistent across devices, while decryption remains tied to the secret you control.
Security without compromising the product experience.
Every major workflow is designed to feel polished and composed while still being anchored in stronger technical defaults.
Zero-knowledge encryption
Your data is encrypted with AES-256-GCM before it leaves your device. We mathematically cannot see your passwords.
Built with Rust
A memory-safe backend keeps reliability and performance part of the platform foundation instead of an afterthought.
Password generator
Generate uncrackable passwords and passphrases with cryptographically secure randomness so reuse stops being the default.
Per-item vault keys
Every vault item is encrypted with its own key and then wrapped by your master vault key for stronger compartmentalization.
Cross-platform sync
Access the same encrypted vault across web and mobile surfaces without switching products or compromising the protection model.
Secure team sharing
Share credentials with teammates using encrypted sharing flows and clearer permission boundaries instead of plaintext workarounds.
Cards and identities
Keep payment cards, identities, and other sensitive records in the same organized workspace as your login credentials.
Biometric unlock
Re-open your vault with biometrics on supported devices while keeping key material in the platform’s secure storage path.
Breach monitoring
Spot compromised credentials sooner and act before password reuse or stale secrets create a wider incident.
Encryption by the numbers, not by marketing copy.
The security story is easiest to trust when the product exposes the important implementation signals clearly.
Authenticated encryption with GCM keeps confidentiality and tamper detection part of the same security layer.
Heavy client-side derivation raises the cost of brute-force guessing instead of leaving it cheap for attackers.
We do not receive your master password or keep your decrypted vault contents sitting on the server.
The service layer is built on a language choice that helps remove a class of memory-safety failures at the source.
Security foundations
Review the full security page for the product-level model behind key derivation, encrypted storage, and admin-aware operations.
Most password managers could read your data. We can't.
Zero-knowledge only matters when it changes the system boundary. The server should not need your secrets in order for the product to work.
