| Fact | Auth0 Guardian | Keycloak |
|---|---|---|
| Purpose | Auth0 Guardian is a mobile app for completing MFA with push notifications or temporary one-time passwords. | Keycloak adds authentication to applications and secure services, so they do not need to store or authenticate users themselves. |
Guardian suits Auth0 users who need mobile push approvals or temporary OTPs for MFA. Organizations building custom authentication apps may also consider its SDKs and MFA API.
Keycloak suits organizations that need centralized authentication, single sign-on, and directory synchronization. It is also relevant to teams able to manage deployment and feature configuration themselves.
