Losing your 2FA codes can be bad. Having backups stolen can be worse. What to do?
I’m using freeOTP, on one device with a backup file on an encrypted drive, not sure if it’s an out of date choice though
FreeOTP is in F-Droid, last version is from 2016. Previous version with the same version number is from 2014. Authy, mentioned in the article is not on F-Droid. This one also seems fine to me : https://github.com/andOTP/andOTP
