When you first open the application up it generates a "Credential ID" and then based off that ID starts generating Security codes. Now if say with Paypal you register that Credential ID and that security code you can then use this app on your smart phone as two factor authentication

Accept, there is one problem

If you ever, for any reason have to reinstall the application, it gives you a COMPLETELY DIFFERENT Credential ID and thus the app will no longer generate codes that will work with your sites you already have setup.

So unless have "I for got my two factor authentication device" which defeats the purpose. You will be totally screwed.

I wish it would some how register with an account so upon re-installation of the application you retain the same Credential ID.

I got totally ****ed by this when I used it on my Paypal account. For security reasons I did not want someone to be able to get around my security key by clicking "I don't have it with me"

Then I formatted my iPod touch 4th gen and went to reinstall the VIP app and got a different ID I was totally locked out of my account. This was before you could also use your cell phone, or in the case of eBay they only allow you to activate one device on the account

So this is just a slight warning for anyone who uses this as their sole method of two factor authentication.

I don't personally use it, but for those that do this is a good heads up!

if the credential ID was generated from a hardware ID for example, then wouldn't this create another security risk if you lose your device or even sell it?

and about creating some account, again, wouldn't that also create another security risk? if someone hacks that account, then they can generate codes too.

I think even though their method is somewhat cumbersome, its still the safest route.

Why not create the credentials ID based on a device ID + a password or pin of your choice.

First allow you to protect opening the app with a password (right now there is none)

second when you go to install / reinstall the application, have it ask for the special pin or password that it then hashes with the device ID to create the same Credential ID.

of course they can do that,and it would be easier,but a random credential id is still safer. the algorithm to generate the credential id from a hardware id and password would be known by looking at the code of the app. someone would just have to know your password,and a piece of static info that will never change, to be able to start generating codes on their own.

Well assuming someone isn't an idiot and wouldn't use a password they always use. how would anyone know what the password would be? I'm no longer using this application because you could VERY easily get locked out of your account.

Lets say you are using this as a sole two factor authentication and the phone dies? Or android crashes or for any reason you have to reinstall the application. Anyone using this would be so ****ed.

I still like a Text message SMS.

What about how Google authenticator does it. They give you special QR codes. That you can save. If you have to reinstall google authenticator on your phone you take a picture of the QR code and you are back in business! :)

As a test i've uninstalled Google Authenticator from my phone and reinstalled it and then took a picture of the saved QR code. It worked beautiful, I almost got a tear in my eye.

Lol, so you blame the app for you being dumb enough not to remove it from your account before resetting your device?

There is that. But also if the device were to get broken or stolen and you had to reinstall the application on a new device. Same issue.

This is the way that keys are supposed to work. ;)

 

If you lose your key you can't open your door. I mean you can't blame a security app for… well, being secure. To get access to your PayPal account again, you will just have to provide some more of your information to prove your identity, which I think is okay if you don't get your devices stolen on a daily basis.^^
