I am considering installing SSO plugins (namely, Discord and Twitter ) on my NodeBB forum. But I am not quite sure about how to integrate this with existing users. My concern is the following : can an user that registered directly to NodeBB use its twitter account (e.g) to login as this specific user ?
I found this old thread on the subject :
From what I understand, if an existing user that used to login directly to Nodebb with the email address email@example.com tries to login with Twitter using the same email address, it will be authenticated as being the classic user ? Is it right ? Does it depends on the SSO implementation ?
SSO is kind of black magic to me, so bear with me if the question is stupid.
