Well, I also have had the misguided idea to use Authy a long time ago, went up around 30 accounts on this shitty software, which used to be good, when it had a MacOS App which was great to avoid having to rely on the phone only, but they didtched that a while ago, and lack of export ability is a nightmare, too.
Shitty software that wants you to keep being locked in, basically.
I migrated most of my 2FA a few months ago and I got lucky because my phone broke suddenly (motherboard issue) 2 weeks ago andthe phone wasn't usable and being repaired for 2 weeks.
And now, I can't even use the 4 last 2FA accounts I still have there 🤣
They really forced me ditch it, for real.
