Here a mockup how it could look like on nodebb.org forum:
Hi I am working on a site that has an existing nodebb forum and we are looking to add features to the site that require a user to have an account. I know nodebb doesn't want you to use it is an auth system and I will have to store user data but is there a way I can use the existing nodebb data so the users don't have to make separate accounts and can login with their already existing nodebb accounts and then I just save their data as a new user. I have been searching the forums for an answer but it seems most cases are either starting a new app and nodebb forum or have an existing auth system and addidng nodebb
I believe nodebb-plugin-oauth may be what you're looking for
Hi @mikewa, we don't have a plugin that allows NodeBB to act as the OAuth2 provider, but I'm interested in creating one if you're interested.
Reach out to us at [email protected] and I'll be happy to discuss further
We did have one in the past, although it is likely not working anymore.
