A different twist to a craigslist scam?

Yeah, what he's gonna do next is have Google send you text with a personal number hooked up to your account, text will have a series of numbers and specifically says to not give out that number to ANYONE. He'll ask for said number. If you give it to him, he'll have access to your account, search history, saved passwords, etc. Some guy tried to pull the same bullshit with me. They are trying to get smarter.
