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