I'm impressed by how PayPal continues to get more complicated but never actually get better.
Me: "PayPal, I'd like to login."
PayPal: "Cool. Oop, you need to two-factor. I've sent your code via text message to this phone number."
Me: "Well that's a landline so it'll never get received."
PayPal: "Oh, our bad dawg. In that case, just give us another phone number."
Me: *gives Google Voice*
PayPal: "Not that one! We can't use that!"
Me: "Sigh..." *gives raw cell number*
PayPal: "Thanks! Okay, we are sending a code to that number."
Me: "Sounds g~ wait: why are we doing this again?"
PayPal: "Two-factor authentication!"
Me: "Right, that security system where..."
PayPal: "You guard against attack by requiring something the user knows and something the user owns. Along two different channels!"
Me: "Right. In other words, me... a potential attacker... supplied the password. And the ID code. Sent to the phone number. That was just supplied by me. The potential attacker."
PayPal: ".... look, do you want your fucking $23 or not?"
