Today, a quick reminder on what is better security in the AWS cloud than adding a hardware MFA key? Adding several MFA keys. Remember that you can add up to 8 hardware or virtual keys.
You can do this for both regular user and root account.
Now you can sleep peacefully, even if you lose or break one key. You will still be able to log in to your AWS account as you can have multiple keys added.
If you add both a hardware key and a virtual device, you will be able to choose which method you want to use when logging in.
