2FA App - Authy

There are many 2FA Apps, Microsoft, Google, Duo, etc. But I select Authy.

Pros

As an end user, I'm not the one looking at how secure a 2FA App is, it is only generating a code as expected. But I need to two major considerations as my experiences.

• Backup - My phone was broken, then I lost all my codes, I don't even remember what they are. Very sad experience.

  Yes, Authy backs up data to their own server.

• Multiple Devices - To make sure my codes won't be lost, then they should be available via multiple locations.

  Yes, Authy can be used in many devices, and can track them in devices list.

• Offline - To make sure I got my own copy on my hand, I need it works offline.

  Yes, Authy has a local copy.

• Acceptable by others - When you hear supported by Google Authenticator, it should work.

  Yes, it supports standard TOTP.

Cons

• Don't know how to remove the code from iOS App
• There is a Default device in devices list, which is quite confusing.
• How to save backup codes? No solution given.
