SAML2 or Security Assertion Markup Language 2.0 is a standard for exchanging authentication and authorization data between security domains.  It enables cross- domain single sign on (SSO) by distributing authentication tokens to users.  

For the security and convenience of our customers, MailRoute supports SAML2 compatible providers as external authentication for single-sign on capability. 

There are two steps to set up single sign-on: the service provider configuration, done in the MailRoute Control Panel, and the identity provider configuration done within your SSO system. 

On the MailRoute Control Panel, login to your admin account and choose External Authentication on the tabs on the left hand side of the screen.





Once you have selected SAML2 from the drop down box, you will see this screen.





Enter the Entity ID data and the Metadata URL from the Service Provider settings listed above.  Click Save.


Next Step:

Configure your SSO system with an Identity Provider.  Providers such as OKTA ( and OneLogin ( are amongst those we support.


How to configure using OKTA please see article here
