It's trivial to remember a very long password.

It's obnoxious to have to enter it on an iPhone keyboard with one hand while trying to drive or whatever on every login to anything. Particularly bad since I'm on a platform with a secure element, protected by tamper-resistant hardware, and relatively decent OS provided APIs to handle this exact problem.

There are good rumors that iOS 7/iPhone 5++ is going to have at least a fingerprint sensor, too, which would then automatically give biometric protection to the keybag as well.

While driving!? Why write that? Have you no shame?

Specifically, it is while at a gate, potentially blocking traffic (because I don't remember all the gate codes, I keep them in 1Password). It's not while actually driving, but close.

The implication of:

  > with one hand while trying to drive

is that your other hand is on the steering wheel actively driving. It sounds odd to say that one is "trying" to idle while parked at a gate.

Give him a break! Commenting on HN using an iPhone while driving is hard enough and now you want him to proofread?

Gate codes might be more appropriately stored on a piece of paper that you keep in your car or with your keychain.
