Set Up Single Sign On with Auth0
This tutorial covers implementing Single Sign On (SSO) with Auth0.
1. Configure the Connection
For Social Identity Providers ensure the Connection is not using developer keys.
2. Enable SSO for the Client
Navigate to the Clients section of the Dashboard. Click on Settings (represented by the gear icon) for the Client to enable SSO on.
Near the bottom of the Settings page, toggle Use Auth0 instead of the IdP to do Single Sign On.
3. Configure SSO Session Length
When the SSO flag is set for a Client, Auth0 maintains an SSO session for any user authenticating via that Client. The SSO Cookie Timeout setting determines how long an SSO session is valid. By default, an SSO session expires in 10080 minutes (or 7 days).
To configure the SSO Cookie Timeout setting, navigate to Dashboard > Tenant Settings > Advanced.
SSO session cookies expire after 3 days of inactivity. For example, if no application (in the same browser) on a user's machine performs a login using the SSO session then the cookie expires after 3 days, even though a server side session might persist. Performing a new standard login would reset the SSO session.
The session inactivity duration (3 days) and is not configurable on the Public Cloud. PSaaS Appliance users, however, can control this account-level setting.
4. Check the User's SSO Status from the Client
Whenever you need to determine the user's SSO status, you'll need to check the following:
- The Auth0
accessToken, which is used to access the desired resource
accessToken, which is calculated using the
expires_inresponse parameter after successful authentication on the part of the user
If you don't have a valid
accessToken, the user is not logged in. However, they may be logged in via SSO to another associated application. You can determine if this is the case or not by calling the
renewAuth method of the auth0.js library, which will attempt to silently authenticate the user within an iframe. Whether the authentication is successful or not indicates whether the user has an active SSO cookie.
