Auth0 Guardian vs PWM

Auth0 Guardian is a mobile app for completing multi-factor authentication on iOS and Android. During login, users can approve a push notification on an enrolled device or enter a temporary one-time password. Guardian-generated OTPs normally remain valid for 30 seconds. The app supports multiple languages and dialects, follows the device language by default, and offers system, light, and dark themes. Users can protect it with a passcode, passphrase, or device biometrics. Organizations can use Guardian SDKs to build similar applications or add Guardian capabilities to their own apps. Push delivery can use AWS SNS, Firebase Cloud Messaging, or Apple Push Notification service. Auth0 MFA API endpoints can enforce MFA at token endpoints and manage enrolled factors. Guardian is available through the Apple App Store and Google Play Store. The free plan is available; paid plans start at 35 /mo, with a 22-day trial.

PWM is a free, open-source password self-service application for LDAP directories. Its web configuration manager exposes more than 500 settings and lets administrators import or export configuration as one file. During password changes, rules are enforced while users type and password-strength feedback is shown. Forgotten-password verification can use email or SMS tokens, TOTP, remote REST, OAuth, or LDAP attributes. Listed directory support includes Generic LDAP, 389 Directory Server, NetIQ eDirectory, Microsoft Active Directory, and OpenLDAP. Authentication options include Basic Authentication, HTTP-header username injection, CAS, and OAuth client single sign-on. REST APIs cover password setting, recovery, policy reading and verification, and user-attribute updates. PWM is distributed as a Java WAR, an executable Java JAR with embedded Tomcat, or a Docker image. The version table lists Java 17 for PWM 2.1 and Java 11–17 for PWM 2.0. Configurable policies include syntax and regex rules, dictionary enforcement, remote REST checks, and shared password history. The listed plan is free.
