I am going to add a new custom autentication in power apps pages in the same way as Facebook works.
Should I use oAuth 2.0 or OpenID connect?

hi @PerL
Microsoft's recommended approach is to use Azure AD B2C as the Authentication method for Portals (which is based on the OpenID protocol)
Please see if this article from the documentation helps: Configure the Azure Active Directory B2C provider (using interface in preview) - Power Apps | Microsoft Docs
