I just switched to Authenticator Pro from Authy and I've been very pleased. It took some time to get my codes transferred over, but now I have android wear support, night mode, and my codes aren't held hostage by Twilio!
Using Authy. Pretty happy with it. It's key feature for me has been the ability to easily restore if you lose, reset or upgrade your device, without having to mess around with your own backup and syncing.
Would suck to reset your phone and discover the sync had failed and the backup was not up to date.
Authy is alright but I found myself increasingly uneasy. No major updates for a very long time and being owned by a giant security corporation, combined with the inability to export my codes, left me feeling like it was enshittification waiting to happen. I wanted dark mode and more control over the icons and organization too
