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
There are some other authenticator apps out there, fully open source, offline, and that support sha256.
I found Authenticator Pro to have the best ui, but many people also use andOTP because it has more features.
Thanks! I'm gonna try out Authenticator Pro.
