Your Passwords. Your Device. Your Control.

Bastion is a fully offline, zero-knowledge password manager built for users who want absolute privacy. Your data never leaves your device — ever.

No cloud sync.
No tracking.
No external servers.

Just strong encryption and complete control.


< Powerful Encryption Standards >

Your entire vault is encrypted locally using AES-256, the same encryption standard trusted worldwide.

Your master password is the only key.

We use Argon2id — a modern, memory-hard key derivation algorithm — to generate your unique encryption key. Your master password is never stored and never transmitted.

This is true zero-knowledge security.


< 100% Offline by Design >

Unlike cloud-based password managers:

• No data is transmitted
• No remote databases
• No third-party servers
• No account required

Everything stays on your device.

If you prefer maximum privacy and minimal attack surface, offline is the gold standard.


< Secure & Convenient Access >

Security doesn’t have to be inconvenient.

• Biometric unlock (fingerprint / face)
• Hardware-backed keystore integration
• Auto-lock protection
• Brute-force defense mechanisms
• Tamper verification safeguards

Your vault locks itself when not in use.


< Why Offline? >

Cloud password managers introduce additional risk:

• Server breaches
• Credential leaks
• Account takeovers

Bastion eliminates those risks entirely by removing the cloud from the equation.

You are responsible for your master password — and that’s exactly the point.

If you lose it, it cannot be recovered.

That’s real zero knowledge.
