BKey is a biometric identity app that lets you prove who you are — without passwords, PINs, or security questions. Your face is your key. Create a secure digital identity tied to your unique biometrics. Log in with a quick face scan. Approve or deny access requests from apps and services — all from your phone. HOW IT WORKS 1. Scan your face to create your identity. No passwords to remember or reset. 2. Your biometric data is processed entirely on your device. Raw images are never stored or sent anywhere. 3. A decentralized identifier (DID) is created for you — a cryptographic identity that you own and control. PRIVACY BY DESIGN - Face scans happen on-device using advanced liveness detection. - Your encrypted data is zero-knowledge — even we can't see what's inside. - No tracking. No ads. No selling your data. APPROVE REQUESTS SECURELY - Third-party apps and services can request verification through BKey. - You review each request and approve or deny with a face scan. - You stay in control of who gets access and when. BUILT FOR TRUST Biometric liveness detection prevents spoofing and deepfakes. Cryptographic identity built on decentralized standards. Enterprise-grade security in a consumer-friendly app.
