Authenticator Options

Folks, was wondering if there is any possibility to have the option of using alternate authenticator apps besides the Blizzard one.
There are several good ones available, (Google Authenticator, Microsoft Authenticator, Authy, etc.
This would make it easier for folks (i.e. have all your accounts on one app), plus most of these offer the option to use a hardware key (Titan security key, Yubico, CryptoTrust, Thetis Fido) which makes it a lot more secure to boot.

Thanks for reading and hopefully this will go somewhere!
