Linking different Auth types

[brilang]

I'm playing with NextAuth to learn how it works, and to figure out how I might want to implement it.

I have two auth methods configured: Email and Google.

When I first signed in with my email address, I couldn't use my Google credentials to subsequently log in. In the URL I noted: OAuthAccountNotLinked

So I went to my database and cleared everything out, and logged in with my Google account first. Then logged out, and back in with email. This worked as expected.

How do I make the first method work? For when a user wants to log in with OAuth credentials instead of email but they registered with email first??

Never mind. Found the answer in the FAQ.
