You implement WebAuthn authentication in Flask by integrating the python-fido2 library to manage registration and authentication workflows, storing discoverable credentials in an SQLite-backed database for phishing-resistant hardware key login.

Phishing-resistant authentication prevents credential theft by using cryptographic hardware keys instead of passwords. You need WebAuthn when reducing phishing exposure and eliminating password-based attacks across enterprise services is required.

Yes, you can provision YubiKey enrollment, manage key revocation, and provision backup keys for enterprise resilience. The implementation supports passkey migration, recovery codes, and detailed audit logging to mitigate account access risks.

Yes, python-fido2 supports discoverable credentials and configurable attestation preferences. The implementation handles full WebAuthn registration and authentication workflows, including sign-count tracking and SQLite-backed credential storage.

The best way to track WebAuthn credential security is by implementing sign-count tracking and generating detailed audit events. This approach logs YubiKey enrollment, key revocation, backup key provisioning, and passkey migration actions.

A key limitation is the risk of lost hardware keys, requiring backup key provisioning and recovery codes. The implementation addresses this using passkey migration workflows, recovery codes, and detailed audit logging for account risk mitigation.
