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 — not even if we wanted to.

How It Works

Three steps to total security

No magic. Just cryptography done right, from day one.

01

Create your vault

Choose a strong master password. We run it through PBKDF2 with 600,000 iterations to derive your encryption keys — entirely on your device.

02

Everything encrypted locally

Add passwords, cards, secure notes. Each item is AES-256-GCM encrypted before it ever touches our servers. We only store ciphertext.

03

Access anywhere, anytime

Your encrypted vault syncs in real-time across every device. Only your master password can decrypt it — not us, not anyone.

Features

Security without compromise

Every feature built with one goal — keeping your digital life private and accessible only to you.

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

Blazing-fast, memory-safe backend. No buffer overflows, no data races — reliability baked into the language.

Password Generator

Generate uncrackable passwords and passphrases with cryptographically secure randomness. Never reuse again.

Per-Item Vault Keys

Every vault item is encrypted with its own unique key, then wrapped by your master vault key. Layered security.

Cross-Platform Sync

Access your vault from any device — web, iOS, Android. Real-time sync keeps everything consistent.

Secure Team Sharing

Share credentials with teammates using end-to-end encrypted sharing. Granular permissions, zero plaintext.

Cards & Identities

Store payment cards, passports, and identities alongside passwords. One encrypted vault for everything.

Biometric Unlock

Re-open your vault with Face ID or fingerprint. Vault keys are secured in the device's secure enclave.

Breach Monitoring

Get notified when your credentials appear in known data breaches. Proactive protection, not reactive panic.

Security Architecture

Encryption by the numbers —
not just marketing copy.

AES-256
Encryption standard

GCM authenticated mode — same algorithm used by governments and militaries worldwide.

600k
PBKDF2 iterations

Bruteforce-resistant key derivation. Millions of guesses per second become computationally impractical.

0
Plaintext stored

We never receive your master password or decrypted data. Zero-knowledge is architectural, not a policy.

Rust
Backend language

Memory safety without garbage collection. No use-after-free, no buffer overflows at the language level.

Why OneLocked

Most password managers could read your data.
We can't.

Zero-knowledge means your master password never leaves your device. We store only encrypted blobs. Even if we were breached or served a court order, your plaintext data is unreachable.
