Tokens contain claims that are statements about the subject, such as name, role, or email address. Beyond the default set of claims that are contained in ID tokens and access tokens, you can define your own custom claims and Groups claims. For example, you might want to add a user's email address to an access token and use that to uniquely identify the user, or you may want to add information stored in a user profile to an ID token.
You can also add a Groups claim to ID tokens for any combination of App Groups and User Groups to perform SSO using the Okta Org Authorization Server. And, you can add a Groups claim to ID tokens and access tokens to perform authentication and authorization using a Custom Authorization Server. See Authorization Servers for more information on the types of authorization servers available to you and what you can use them for.
This guide assumes that you:
- Have an Okta Developer Edition organization. Create an org for free.
- Have an OpenID Connect client application in Okta with at least one user assigned to it.
- Have a group in Okta with at least one person assigned to it.
