I was surprised to find Authy in the "Avoid" column of the 2FA apps in Android. Anybody knows why? I prefer something open source like Aegis that I can backup myself but didn't hear anything bad about Authy in particular.
Authy was my escape from Google Auth.
I avoid Authy for a different reason: after upgrading phones, my backup password (which is 100% correct, trust me) is not unlocking my archive. I switched over to iCloud Keychain and will never look back.
