WebAuthn · Authenticator apps · PHP account security
I add or repair WebAuthn passkey registration and login, site two-factor authentication, authenticator QR enrollment, and server-side TOTP validation while connecting each step to the existing account, session, role, and recovery rules.
Senior PHP & Backend Developer
Focused Passkeys & Two-Factor Authentication capabilities
Each capability is scoped against the installed version, hosting, current behavior, and surrounding customizations before implementation begins.
Connect browser credential creation to an authenticated PHP account with the required challenge, relying-party, and credential state.
Implement a passkey sign-in path that validates the authentication ceremony and establishes the correct application session.
Add an account-level enrollment path that provisions the authenticator secret, presents the QR setup, and confirms a valid code before activation.
Validate time-based one-time passwords on the server and apply the agreed second-factor gate to protected account actions or login.
Fit passkeys or TOTP into current email login, SSO, verification, permissions, and user-interface behavior without creating competing account rules.
Clear service boundaries
These boundaries preserve the difference between evidenced Passkeys & Two-Factor Authentication work and a broader service that has not been claimed.
Passkeys require a correct HTTPS origin, relying-party identity, domain context, browser support, and credential lifecycle. Local or temporary environments may behave differently.
The QR code represents sensitive enrollment material. Storage, display, confirmation, re-enrollment, reset, and support procedures must follow the agreed account policy.
Lost-device, factor reset, administrative recovery, remembered-device, and enforcement rules must be defined rather than silently invented during implementation.
Adding passkeys or TOTP improves a defined account flow but does not claim penetration testing, formal security certification, or elimination of every account risk.
Passkey, WebAuthn, site 2FA, authenticator QR enrollment, and TOTP validation are confirmed experience. Representative authentication and SSO projects provide related product-flow evidence without unsupported security metrics or certification claims.

Passkeys & Two-Factor Authentication delivery process
Credentials are requested only after the scope and access requirement are understood, using an agreed secure channel.
Review registration, login, sessions, SSO, verification, roles, account settings, recovery, and the exact places where a factor is required.
Agree enrollment, optional or required use, supported users, fallback, reset, session behavior, and acceptance checks.
Connect challenges, credential or TOTP state, QR enrollment, validation, sessions, permissions, and interface feedback.
Test invalid, expired, missing, repeated, canceled, unauthorized, and unsupported-device states alongside the normal path.
Verify the production domain and HTTPS behavior, protect configuration, and document support or reset steps included in scope.
