Hi. I was trying to set up 2FA in my settings, where there is a button named "2FA installation link." I right clicked on the button, copied the link, and put it into a QR code generator. I scanned it with Twilio Authy on my phone to add it. To my surprise, when I tried using it to log in, the generated codes simply do not work. I have 20ish entries on Authy and they all work, with the Lemmy accounts being the outliers. I have also tested the 2FA on my other account at feddit.nl, and it doesn't work with Authy either.
So, I tried using Google Authenticator instead. I used it to scan the very same QR code, and it spits out different codes from those generated by Authy. The ones generated by GAuthenticator work, whereas the Authy ones don't work. I wonder what the issue is?
Edit: grammar
If twilio doesn't work but you don't want to use Google, try Aegis or Bitwarden. Both available on f-droid. For totp on Bitwarden you either need to self-host the database using vaultwarden or pay for the pro version.
Thanks for the suggestions. I already use BitWarden, but I use the free tier and sadly self-hosting is not really an option for me (for now). I decided to use Authenticator Pro as suggested by @isolatedscotch@discuss.tchncs.de, and I'll import the accounts maybe this weekend.
By the way I think I should clarify that I'm not a libre extremist trying to avoid everything Google (yet. maybe I'll become one in the future) I just want to slowly move away and also not start using Google services that I don't already use.
Understandable, best of luck if you want move to the "libre extremist" side. It is a very liberating experience :)
