How would I log in from a friend's computer with Persona? How about from an Internet cafe; how safe would it be? Persona looks like something that lock's you into a certain device or at least makes it harder to log in on device's that are not your own.

I'd rather they made OpenID less scarry (to average Joe) instead.

Logging into a different device is not a problem, you just get a different certificate in that device's browser and it allows you to login in the same way.

When you use a computer that's not your own, Persona keeps the session time very small. Of course, when you're done using that computer, you should ideally clear cookies, just like you would if you used OpenID or Facebook on a shared computer.

Please try this today. It's one main reason The Times uses it on their Crossword product...

This is safe on a public computer or shared device, if you logout.

Persona also has some UI around public versus personal devices.

You really shouldn't login from any non-secure terminal. I have catched even pros doing that mistake with production systems. It's major fail!

Major fail or not a good part of the world does not own their own computer.
