FAQ

Common Questions

Which browsers support WebAuthn?

Chrome 67+, Firefox 60+, Safari 13+, Edge 18+, and all major mobile browsers. The kit includes a progressive enhancement fallback — users on older browsers get a secure OTP fallback automatically.

Do users need a hardware security key?

No. Platform authenticators (Face ID, Touch ID, Windows Hello, Android biometric) work out of the box. Hardware keys (YubiKey etc.) are supported as an option for high-security use cases.

How do you handle account recovery?

The kit includes three recovery flows: backup passkey (registered at setup), admin-initiated re-enrolment, and email OTP with manager approval. All flows are DPDP-compliant and fully logged.

Is this production-grade or just a demo?
