Using the System Console, Mattermost Enterprise and Professional customers can migrate OAuth configuration to the OpenID Connect standard. A one-time, one-click conversion tool is available within the existing OAuth 2.0 page. You can also go to System Console > Authentication > OpenID Connect.
Select Convert to OpenID Connect to migrate your active service provider configuration to the new standard. No further changes are required.
Inactive service providers configured for OAuth 2.0 are also migrated to the new OpenID Connect standard.
