If you worry so much about security concern since Authy have account/cloud feature
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.
I didn't know that about Authy. I will try to move to a different software. Which one do you recommend?
I prefer to keep my 2FA in the cloud in case I lose my devices (i don't keep funds under those 2FA accounts, just a lot of accounts with basically zero balance).
Can I keep my backup codes in Aegis servers?
Authy is amazing for me, because I keep my 2Fa codes in my android and in my windows devices. I just disable new devices, and I feel very safe about it.
Can Aegis disable new devices?
