From the menu select Settings then select Authentication. Under the Authentication method section click OAuth.
In the next screen, enter the credentials provided by your OAuth provider, using the table below as a guide.
Use SSO
Enable SSO so that the OAuth provider won't be forced to ask for credentials when users are in a current logged-in session.
Hide internal authentication prompt
Hide the ability to log in through internal authentication. Note that when external authentication is enabled, only the initial admin user can log in with internal auth.
Automatic user provisioning
If toggled on, users who exist at the OAuth provider's end will automatically be created in Portainer (you can define a default team to put those users in while this option is on). If toggled off, you'll need to create users in Portainer manually.
If you toggle Automatic team membership on, you can choose to automatically add OAuth users to certain Portainer teams based on the Claim name. Claim names will be matched with teams or you can manually link a claim name (using regex) with Portainer teams under the Statically assigned teams option. You can also define a Default team for users who don't belong to any other team.
In addition, you can enable the automatic assignment of admin rights to specified groups if desired.
When configuring Microsoft Entra ID (Azure AD) as the OAuth provider, you will need to use the group's Object Id value for the claim value regex instead of the group name:
Portainer provides pre-configured OAuth provider options or you can set up your own custom OAuth provider. Each of the pre-configured providers can have their configuration overridden if you need to make changes to the Portainer defaults.
Configure your OAuth provider using the table below as a guide.
Tenant ID
Enter the ID of the Azure Directory you wish to authenticate against. This is also known as the Directory ID.
Application ID

Application key
Enter the secret key for the OAuth application.
You can find these details using the following steps:

After creating the Registration, the screen below is displayed. Use the provided Application ID in the respective field in Portainer.
Click on Certificates & secrets then click Client secrets, Click on New client secret. Add Description and choose Expiry date, then Click Add.
The secret will then be generated for you. Use the Value as the Application key in the respective field in Portainer.
Click on API Permissions and Add a permission. Select Microsoft Graph in the Request API permissions screen. Select Delegated permissions and add email, openid, profile permissions.
