im using my own oauth flow from backend side i.e spring boot, now the thing is everything happens at backend, i just need to redirect my client to backend and from there it takes the google acc and returns me the jwt token upon success. Now how do i integrate this with next-auth?

Make the auth on nextjs, later u can make fetchs to the backend and pass the session...

Also u can use a db adapter to access data from ur backend https://authjs.dev/getting-started/adapters

@ReverseGem7 So you are saying to authenticate the user on nextjs instead of spring boot?

Yes, in my opinion this approach is more simple and fast

thanks @ReverseGem7
