As previously explained, OpenAI, recently, disconnected their SSO integration; instead, silently replacing it with an e-mail address inherited from the user’s OpenAI account, and no password bound by default. Because I utilise an e-mail alias service for each account, this required that I correctly presume that this had occurred:
This is not an intuitive process for the average user (not that I’m special, though).
I would prefer to also be able to utilise the account’s id, but that appears to be less popular than usernames, whenever I discuss it. Additionally, it would solely be in addition to this, so it’s probably out-of-scope.
