How to get an access token using b2clogin.com instead of using login.microsoftonline.com without user authentication?

Question

I use Microsoft Graph API to manage Azure AD B2C users.

In order to get access without user authentication, I use the following API to get an access token.

https://login.microsoftonline.com/<my-tenant-id>/oauth2/v2.0/token
grant_type=client_credentials
scope=https://graph.microsoft.com/.default
client_id=<my-client-id>
client_secret=<my-client-secret>

I found that login.microsoftonline.com was deprecated as described in the article below.

https://azure.microsoft.com/en-us/updates/b2c-deprecate-msol/

I should use b2clogin.com, but I still use login.microsoftonline.com.
I couldn't find any documentation on how to get an access token using b2clogin.com instead of using login.microsoftonline.com without user authentication.

Where is the documentation?

Or can I use login.microsoftonline.com to get an access token without user authentication?

Thank you.

Hi @WataruUmeda-8571,

I see that you are using client_credentials flow. This flow is not yet supported with b2clogin.com.
