Proton Authenticator vs WatchGuard AuthPoint

Proton Authenticator generates time-based one-time codes for two-factor authentication, adding a code at login to help secure accounts. It can display codes without an internet connection, and a Proton Account is not required to use it. Signing in is optional and enables code syncing across devices. Users can import codes from Google Authenticator, 2FAS, Aegis Authenticator, Bitwarden Authenticator, Ente Auth, and LastPass Authenticator, then export their codes from the app. Backups can be stored locally or in the cloud, with end-to-end encrypted sync between devices. Proton says its servers cannot access synced data in unencrypted form; when sync is on, entries are protected with 256-bit AES-GCM. The app is open source, and its vault can be unlocked with face or fingerprint recognition. It is available for Android, iOS, Linux, macOS, and Windows; Android is also available through F-Droid. Proton Authenticator is free on all listed platforms, with no ads or tracking.

WatchGuard AuthPoint is a cloud-based multi-factor authentication service that checks users before they access computers, VPNs, cloud services, and applications. Verification options include push notifications, one-time passcodes, QR codes, hardware tokens, and phishing-resistant FIDO2 passkeys. Access policies can consider device, location, behavior, time, and device DNA. An application portal provides access to SAML and OIDC apps, and WatchGuard lists more than 130 third-party integrations, including VPN, Microsoft Entra ID, and cloud applications. The service is managed through WatchGuard Cloud, which supports multi-tenant administration for service providers. An optional Gateway connects AuthPoint with RADIUS clients, Active Directory or LDAP, and the ADFS agent; it cannot be installed on Windows servers with FIPS mode enabled. AuthPoint is licensed per user, with pricing available from a WatchGuard reseller and no free plan. A 30-day trial for up to 250 users is listed. The mobile app supports Android 7.0 and higher and iOS 14.0 and higher.
