To begin your journey into absolute data sovereignty, first install the Keypher Extension for your preferred browser. Keypher is available on Chrome, Firefox, Edge, and Opera.

Upon initial launch, you must define your security architecture. Keypher offers two distinct modes:

• Local Isolation: Your vault data remains strictly on your local device. No synchronization, zero attack surface on external nodes.
• Cloud Harmony: Enables end-to-end encrypted synchronization. Your data is sharded and distributed across the Keypher network, ensuring access on all your devices without compromising zero-knowledge principles.

Keypher does not store "accounts" in the traditional sense. When you sign up, you define a Master Password which is the primary seed for your cryptographic blueprint.

Important: Keypher has no recovery mechanism. If you lose your Master Password, your data is mathematically locked forever. We never see your password.

Your dashboard is the central hub for all stored assets. It is designed for clinical efficiency:

• Global Search: Instant filtering of records via metadata-blind indexing.
• Categories: Quick access to Logins, Notes, Identities, and Payment Cards.
• Security Snapshot: Real-time health metrics of your current vault state.

To add a new record, click the (+) NEW button in the top right. Select the item type to trigger the appropriate input matrix:

Every record in your vault can be modified or safely removed at any time.

Bypass weak, predictable passwords with our Entropy Engine. Use the toggle matrix to define complexity (Symbols, Numbers, Casing) and watch the entropy strength update in real-time.

The Protocol Health Scanner continuously monitors your vault for security deficiencies. It highlights reused passwords, compromised credentials (via HIBP integration), and weak entropy patterns.

Ultimate control includes the right to vanish. The Protocol Nuke is an irreversible tactical command that wipes your entire cloud existence within milliseconds.

Configure your Keypher experience. The Settings hub allows for granular control over:
