Agreed.: With all of the above.: MFA is mandatory in most countries for banking but Email/SMS/...-stuff is inseure.

As with all "https://en.wikipedia.org/wiki/Trusted_Platform_Module"-based authentications the basic idea is, that the TPM-chips are built in a way to be burned up by the x-rays produced by electron-microscopes trying to read out their keys.: It is like in Mission Impossible.: https://spymovienavigator.com/filmclip_type/this-message-will-self-destruct .

So, one can use Microsoft/Google-Authenticator, which will not be giving out the keys, but just a signature signed with the key.
Both of them are available for all Apple/Android-smartphones.
Attached You can find a short overview assembled by ChatGPT showing how to implement this.
If You have Your own Windows-Azure-Tenant at https://login.microsoftonline.com (i.e., Work- and School-accounts) You can even use Entra-ID B2C for it, implementing it with JSON-based Workflows with almost no code (e.g., "https://aka.ms/aadb2c", "https://www.youtube.com/watch?v=h5bxhZRF4mI").
