Test the SSO Connection

Once you have configured your IdP and the Twilio SSO Profile, then it is time to test the SSO Connection to make sure that login with this SSO Profile is working. The below steps describe how you can test the SSO connection -

Enter the email address of a managed user (other than you) to send the test SSO email. Please note that this should be an existing user in your Twilio Organization

Please make sure that you have added this user to the new SAML SSO application (i.e. assign them permission to login to the Twilio Console app from your IdP) that you configured in the previous steps
The user will receive an email from Twilio informing them that you have chosen to send the email to them. The email contains a link which the user has to click to test the SSO connection

Upon clicking the link the user will be taken to the Twilio login page. If they had an active session then that will be closed automatically.
On the login page when the user enters their email address and clicks 'Next', they should be redirected to the IdP that you have configured for authentication.
On the IdP side, the user will enter their credentials to authenticate them at the IdP. If the user already has an active session with the IdP then they may not be required to do so.
Once authenticated at the IdP end, the user will then be redirected back to the Twilio Console with the SAML response and assertion from the IdP.
If the user can access the Twilio Console successfully then that means that the SSO configuration is working properly and the test is successfully done.

After getting the login result from the user, you should mark the result in the SSO Configuration UI in the Admin Center to proceed forward to the Enforce SSO step.

Note that if the Test SSO wasn't successful then you won't be able to proceed to the next step for enforcing SSO. If the test SSO login didn't work, then you can visit the Troubleshooting Test SSO Failures page to find out the error and how to fix it.
