Welcome! Thanks for letting us know. I'll check with @Wimpy since these were set up a long time ago.
Apologies that your first post was marked as spam; a member of the community erroneously must've mistaken it as such (especially as there has been a influx of spam lately)
The conclusion is that we don't really use Facebook or Twitter X and not really advocators for it.

If anyone did previously (and exclusively) logged in with Facebook/Twitter:
I believe your account should be using the email associated with the social account, try using that to login or reset the password. If you can no longer do so, or forgot, please get in touch with a moderator and we can discuss the options.
