Wildcard domain
I have an unusual use case for auth: my authentication database is shared between multiple apps running on different subdomains. Accounts created in one app also exist in other apps.
This almost works. However, I’ve stumbled upon a weird problem: sometimes both Google and Email/Password authentication fail.
Google reports an incorrect redirect_uri, while Email/Password reports an invalid origin.

Session Caching with Custom Fields Workaround
I've been using Next Auth and was thinking to switch over, however the line below is making me hesitate. I do not want to hit the db on every request, but I also want to use custom fields such as roles. Is there an alternative or work around for this?
...
Session caching, including secondary storage or cookie cache, does not include custom fields. Each time the session is fetched, your custom session function will be called.

OAuth custom headers in token request
Hi!
I'm trying to integrate Vipps authentication using the genericOAuth plugin. Vipps requires specific headers (like Merchant-Serial-Number, Ocp-Apim-Subscription-Key) to be sent with the token exchange request (when getting the access token).
I see the discoveryHeaders option, which is helpful, but I can't find a way to add headers specifically to the token request itself within the genericOAuth configuration....
nextjs + nestjs
i have a nextjs app with better auth setup.
what would be the best way to handle auth verifcation on the side of the nestjs backend ?...
Solution:
Hey, there is https://github.com/better-auth/better-auth/pull/1548 coming, but there is also comment from user juandl , where he explains how he implemented it.

Solution:
run npx @better-auth/cli generate and update your schema manually.
Migrate: This command creates the required tables directly in the database. (Available only for the built-in Kysely adapter)...
