Please add 2FA to any/all fields that require a user type in their phone number.
If we examine how very important email validation is one is left to wonder why modern tech companies do not also verify phone numbers?
Consider the benefits:
"Unsubscribe" for phone numbers
If a user wants their number removed from ANY account they can call into GoDaddy tech support and request a 1 time text message be sent to the number, if they confirm removal at that number then that number is removed from that account.
Implementation of this idea could be an innovation that GoDaddy will get industry recognition for, your shareholders will be pelased and the public will applaud you for wise decision making.
How it should work:
This is no more complicated than how we now do email validation. Similar challanges exist such as "spam folder = missed calls" or "email relay = phone routing" but they do not hold companies back from understanding how important a real email address is.
Please then consider a validated phone number is just as important as a validated email address.
