MyBB Community Forums

I need to access the Admin panel for my forums but the Authenticator code isn't working. I have full access to the server but would rather not mess about with database stuff if possible (MySQL is intimidating, lol). Any good workarounds for gaining access again?

My installation of MyBB was last updated 13 December 2017, but I've continued updating the server, so over this period it's possible something broke on its own. Or someone found an exploit, broke in and changed the Authenticator key, but this seems unlikely as there's been no evidence of a breaking-in.

Update:
For what it's worth, I've discovered that failing to log into the admin panel five times results in myself being emailed an activation code. This doesn't help me get past the Authenticator thing though.
