You're absolutely right, Dabbsy
All these websites that are pretending to "secure" my login by asking me my phone number for 2FA, and then they get hacked by miscreants and where's my security now ?
If I wanted my phone number to be available to the general public, I'd not have chosen to subscribe to the liste rouge, the French version of Do Not Call.
You're just a website. I can manage my own security better than you, thank you very much.
