Authgear vs Duo Mobile

Authgear is an identity-as-a-service platform for authentication and user management in web and mobile applications. It supports sign-in with email, phone, username, password, one-time codes and magic links, along with mobile biometrics, passkeys and multi-factor authentication through SMS, email or TOTP apps. Identity provider options include Google, Apple and Azure Active Directory. It offers single sign-on across web and mobile applications, including SAML SSO for web apps.

Its user-management portal supports password resets, account locking, profile management and scheduled deletion or anonymization. Developers can use SDKs for React, React Native, Ionic, native Android, iOS and Flutter, as well as OAuth 2.0/OpenID Connect and Admin, User Import and User Export APIs. Authgear describes itself as open source and supports self-hosting; its hosted service is currently in the USA on Google Cloud Platform infrastructure. Plans include a free tier and paid service from $50/mo. The free tier includes two applications, two admin seats, one-day log retention and community support.

Duo Mobile provides two-factor and multi-factor authentication for company and personal data on iOS and Android phones and tablets. Users can approve or deny sign-ins with Duo Push, or enter time-based passcodes generated by the app. It also supports third-party TOTP accounts, biometrics, and passcodes. Duo Restore backs up and restores Duo-protected accounts when a user changes devices, and Security Checkup provides a mobile-device security score through app notifications. For organizations, Duo connects with legacy infrastructure, custom apps, VPNs, SaaS tools, and offline devices. Integration methods include RADIUS, SAML/OIDC, Duo Authentication Proxy, and direct API connections. Adaptive policies can consider user role, location, application, network, and device health. Duo says it keeps private keys on users’ devices in a tamper-proof secure element and does not store passwords. The free plan covers 10 users; paid plans start at $3.00 per month, and a 30-day trial is listed. End users needing enrollment or troubleshooting help are directed to their organization’s Duo administrator.
