It seems that you are encountering two issues: the error related to the UserCredentialPolicy and access restrictions when trying to view the Authentication Methods policies.
- UserCredentialPolicy Error: The error indicating that the UserCredentialPolicy does not allow the use of Temporary Access Pass (TAP) suggests that the user you are trying to sign in with may not be in scope for TAP use in the Authentication methods policy. Ensure that the user is included in the policy that allows TAP usage. You can check this by navigating to the Authentication methods policy settings and verifying the users and groups included.
- Access Error: Regarding the access error when navigating to Entra ID > Authentication Methods > Policies, the Privileged Authentication Administrator role may not provide sufficient permissions to manage these policies. You need to have the Authentication Policy Administrator role to update the TAP Authentication methods policy. Ensure that you have the correct role assigned to your account to manage these settings.
To resolve these issues, confirm that:
- The user is included in the TAP policy.
- You have the Authentication Policy Administrator role assigned to your account.
If you continue to face issues, consider reaching out to your organization's administrator for further assistance.
