Apple Login Error "invalid_client"

Tried this with passwordless and password login. I can connect to Apple, but when the callback happens is when I get the invalid_request / invalid_client error. Google and FB logins work great.)

I’m sure I’m missing something simple. I’ve googled for hours so I’m posting here in hope for some help.


Hi @tadpreston,

The invalid_client error is thrown if Apple was unable to authenticate the client (your application registered with Apple). Have you confirmed the Services ID (Client ID), Apple Team ID, Client Secret Signing Key, and Key ID in the Apple developer console? docs:

Hi Stephanie, thanks for the quick reply!

Yes, I checked those many times over and it appears to be set up correctly, both on Apple’s side and Auth0 …

I found the error. Another teammate had changed the KeyID to another cred we had in Apple.
