moin moin,

I've been recommending for years that web sites should not be given your
phone number for 2 factor authentication. First of all, they don't need
your phone number :). Secondly, it's not secure.

Now the NIST agrees.

If you're setting up a service to use 2FA, please do not include SMS as
one of the options.

ciao,
