Thanks for the PR @jgeurts 💚 . To have a bit more context, could you explain what are the problems you're trying to address when exporting these types ( as maybe there's no need )?

Bear in mind that the actual types still live at DefinitivelyTyped and the types here are part of a migration that is WIP (so even if we merge these updates, you won't be able to benefit from them just yet 😌)

[jgeurts]

I have a custom adapter that defines functions for verification requests. Currently, I duplicate the type definitions, but it would be handy to import them from next-auth. I’ll add a PR to DefinitelyTyped in the coming week, but figured I’d start here in case this goes through before I make the other pr. Hope that helps!

Sounds good 😊 , I think we can merge here and no need to raise the PR on DefinitivelyTyped.

Would wait to merge until we reviewed #1690

As far as I can tell, all these will be redundant/are addressed in #1690, so closing. Tell me if something is missing still!
