Big issue with the authentificator

[Lilseph]

This is weird, but I have had this issue before. I only was able to fix it by removing it with the code you sadly don't have. I know their customer support can help you as well, but yeah... they won't be available either. Do you still have the registration code in your main, trying to delete the app and re-register it again with it? I don't know if they are one-time use. Have you tried adjusting the time in your phone too?

Deleting the app will desync it and you may not be able to add it again at all without the emergency code. I couldn't.

I'd suggest checking your phone time to make sure it's correct. That is a huge drift and shouldn't happen unless the phone time is way off. Normally phones get their time from the network, but something may be wrong in this case. You can compare to a site like https://www.time.gov/ , which is run by the US government and comes from one of the core NTP servers (which get their time from an atomic clock). It will be accurate enough for this purpose.
