Facebook Introduces One-Time Passwords

angry tapir writes "Worried about logging into Facebook from a strange computer? There's now a way to get into the popular social network without entering your regular Facebook password. It's called a temporary password. To use it, users must list their mobile phone numbers with their Facebook accounts. They can then text a number from their phones and Facebook sends back a temporary password that is good for 20 minutes. The service will be available worldwide in the next few weeks."

      There is at least one Swedish company that does deny them, SF Bio (the largest movie theater chain in Sweden). However, in their case there is a good reason; to get the tickets you've bought online with your credit card you have to swipe the same card in their ticket printing machines. You could definitely come up with another way to get the tickets once they are bought, but as long as you have to have the credit card with which you paid to get the tickets, one-time cc numbers are probably out of the question.

      In this case it could be both. I mean, it's a really good system for protecting your password, but it also gives your cell number to Facebook which they really like. If you use a lot of public computers this becomes kind of a win-win. You get increased security, Facebook gets your number. If I want to access Facebook and I have my phone I use the Facebook app, so for me this isn't very useful.

    I seem to remember some sites using Verified by Visa and then abandoning it. Perhaps they found that shoppers were abandoning their shopping carts after having set up VBV before and then forgetting their VBV username and password.

    Well, few reasons.

    1) Merchants love it because the customer gets stiffed with the charges (you can't chargeback a merchant if it was done via 3DS (3D Secure, aka Verified by Visa and MasterCard's equivalent). I only do VBV on a merchant I know. Unknown merchants, I'd probably trust Paypal a bit more.

    2) It seriously screws up with NoScript. I keep forgetting to enable the 3rd party site which usually results in screwing up the checkout process.

    3) It makes it harder to do "one-click shopping". If you're a merchant that gets a lot of impulse buys, the more steps betwen "I want it" and "We got your order, it'll be shipped soon!" is more chances the user will cancel the order prior to completion. (And this is a very important point)

    4) It's extremely insecure, and can offer a great way to phish. Heck, we've got previous Slashdot articles on the subject. Why "Verified by Visa" system is insecure and Net Shoppers Bullied into "Verified by Visa" program.

    5) Forgetting your password can get your credit card locked out.

    Quite honestly, 3DS is just another form of Wish-it-was two-factor security. It pretends to be more secure, but in reality it isn't.

    There are two ways to do it properly - you could SMS people a password, but that screws with people like me who don't always carry their cellphone around, or perhaps build in an RSA key thingy inside the card itself. Chip cards (which have their own issues - really - the PIN's in the chip and the chip sends an "OK" or "Failed PIN" response - not any form of challenge-response packet to the bank, who should know your PIN, not your card) have powerful enough processors to do some RSA token like task. Given we can buy a calculator for under a dollar, there's no real reason why we can't have credit cards with two-factor support on them (and no PIN needs to be stored - the card will generate a code based on the entered PIN which the bank can validate).
