There is no good reason to ever use Authy. They have the ability to lock your out of your Authy account, thereby locking you out of every account which you use 2FA for, which is a massive red flag. And the only way to unlock your account in such a scenario? Complete KYC with them. Oh, and they track your activity and share that info with third parties.

It's like someone said "Instead of keeping the keys to your house yourself, give them to me and I totally promise I'll let you use them when you need to. But I'll also let a bunch of other people know whenever you use them." It's a massive privacy and security risk. There is no good reason to use Authy when there are a multitude of open source apps which allow you to store your 2FA codes locally.

Both are Android only, while OP uses iPhone/iOS. This is why I suggested he uses Tofu, which is the best open source 2FA app for iOS: https://www.tofuauth.com/
