Reltio helps you to perform authentication operations for a user.


Authentication is the process or action of verifying the identity of a user or process. It is the act of validating whether users are who they claim to be. For example, to log in to an application, the username and password entered are authenticating factors. You are allowed to access the application only if you provide valid username and password.

Unique User Identification

In Reltio, email address is a unique identifier for user identification. A user with an email address is given a specific set of roles. An email address can be used only once. If you assign the same email address (irrespective of the case) to another user, and the new user attempts to log in, the following error message is displayed:

This login is already in use by another customer. Please use a different account.

For different customers/tenants, it is recommended to set up and use accounts with different email addresses.
