I've used the authy mobile app for a while for OTP tokens, but have the backup/syncing turned off. I noticed that they have a desktop app, which would be a lot more convenient most of the time, but I'm wondering if there has been any security research into their implementation and if this is a good idea or not.
It looks like in order to use the desktop app you have to enable authy's syncing between devices. This seems exactly the same as a password manager - the OTP seed syncs between devices, encrypted with a master password, the same as my randomly generated 1Password passwords. And I would likely store the authy master password in 1Password anyway so I don't have to remember a new secure password.
So my question is, is this worth using or would it be about the same to just turn off 2FA since it's approximately the same data model and no longer an independent second factor?
