Unlink Google authentication

[owrh]

We have an odd case where a member can’t log in. Their account is linked via Google, but when they try and do the OAuth dance they get 500s. All the settings in the Admin area look fine – the account is active etc. We don’t have this issue with other accounts, but the Google account in question has been recreated – i.e. a new Google UID where the email address is the same. Perhaps this is related.

Anyway, in order to try and fix it myself I wondered whether it’s possible to unlink an account from Google so it’s just a standard, email/password authentication?

[owrh]

I’m still interested in the answer to this, but for the time being I’ve just ‘anonymised’ the user and invited a new one. This is slightly annoying since all the old posts are now from an anonymous account and not attributable to the original author, but at least the person can log in again.

Issue: user changed google account and can't connect thru his profile

I have one very active user on my discourse. Everything was fine until a moment when user changed surname and changed his email account. He logged on to discourse thu google authorisation. He changed his email in profile however linked google profile is pointing to an old google account and therefore he got 500 error as in profile email is new but linked google profile is pointing to an old email . How to overcome this issue?
