So... I was testing 2FA in my main profile (Aurelius). I turned it on and realized that it requires a 2FA app. I never turned it off in my settings, but now it requires me to provide 2FA even though I have no way to authenticate
All this to say, I added 2FA in the Quiblr web app. In the name of speed, I built it blind (no testing - since I dont have Lemmy 2FA). But the documentation looks simple enough.
Feel free to take a look and see if it works for you now!
