    paypal security fob thing

    Hello,
    Wasnt sure where to post this.
    Ive just ordered one of those security fob things for £3 from paypal for extra security. of course then I was started wondering how the technology works.

    the keyfob is a stand alone device that generates a code every 30 seconds. how does paypal server know what that code is?

    when i was doing some computer work for someone i noticed they had one of those devices for hsbc. I cant seem to get one myself thou. does anyone who is a hsbc customer have one of these yet?

    thanks in advance

    Looks similar to Barclay's Pin sentry, which AFAIK works by the generator being tied to your account via a serial number. They have a set number of codes that are given out randomly. Each time one is used it is removed from the server.

    I think that is how it works anyway...

    Looks very similar to the RSA SecuriID fob's, I would imagine there based on similar technologies.

    Re: paypal security fob thing

    So basically like a lot of one-time pads?

    The Natwest one requires your card to generate the secure code, so no doubt it's card specific (that's a given...).

    If you have to pay for it, then i would assume they link it specially to your account.

    Re: paypal security fob thing

    I've had one of the keyfobs for 6 months or so.

    It works as you would expect. You can log in with your normal password and add the keyfob PIN to the end of it.

    The ebay 'lost/forgotten keyfob' feature is fine - it calls you on the 'phone number on your account and gives you a one-off PIN to use. PayPal, however, has security questions which is a big flaw in the whole system.

    Re: paypal security fob thing

    Hello,
    I receved my paypal security thing today.
    edit:
    the security card broke and instead of displaying 7 random digits it decided to display ten 0's after around 5press's of the button
    I rung up paypal and talked to a human by saying "agent". Eventually after some more options of what to talk to the agent about i got through and explained the sitaution and i will receve a keyfobe security key within 7-10 working days. at least those devices are better made and doesnt feel like it is going to break.
