If, upon logging into the Aura console, you see this error about unauthorized access:
It means you are logging in with a different identity than you first used when creating your Aura account. Aura gives you the option to use your email and a password, or your Google credential, to access the service. But once you've chosen one method you must continue to use that same method in the future.
If you've lost access to your original credentials or need to otherwise switch which option you are using for authentication, please open a support ticket. We'll be happy to help you resolve the issue.
