I have configured apple account for third party login using social account but when i test the connection it takes my credentials and fail the authentication by throwing invalid client error. In social account setting all information like client, key id etc are correct, what i am missing? in authentication method i configure password but not the passkey does that making any issue?
That error suggests an invalid client ID/secret.
You can determine which client ID is causing the error by looking at which provider is throwing it. Is Apple rejecting the call or is Auth0?
