Ratings and Reviews
GOAT contender, only missing Apple Watch app
Very decent app, good looking, works well and fast, the way it works with browser extensions is perfect, supports backup and export. Nothing to complain about it really. Adding Apple Watch support would make it greatest of all time, and would allow me to uninstall OTP Auth for good.
Developer Response ,

Developer Response ,

No encryption while in the icloud
This is store in the icloud with no encryption. It is store as any other archive. If theee is a leak, all passwords and 2FA codes are in the same place.
An extra layer of security coming from the 2FA app is neccesary.
Other apps has it, just choose a password, then when installing the app in a new device yo just write it once.
If you do that, I would change to this app
Developer Response ,
Hello, fortunately, our app doesn't need any additional encryption, it is already protected. It doesn't require an internet connection, and we don't store any of your data, so everything is as safe as possible. As for iCloud, it has its own protection against hacking. :)
