I want to use the Google Credential Manager for a sign in method in my android app. For this I need to create a new OAuth client id credentials in the google cloud console. During the registration for using the google cloud console I am asked to provide my credit card information. Now I am wondering if using the google credential manager is free of charge or could their be potential costs?
I am not planning on releasing the app on any app store, so there will be barely any users.
