Gmail doesn't do this? Hell, I got so annoyed by those messages that I did link my phone number to my account, only to then have it start asking me to link a second phone number to the account. And boy am I glad I linked my number, because now I get to go through the whole authorization process with every device and browser I use, for both of my Gmail accounts. I swear Google texts me more than humans.
