Improve the One-Time Password app for iPhone users.
I didn't install the app yet, after reading the reviews from users I'm unsure if I want to use the app or not.

Pros: Keeps your acct safe

Cons: If you delete the app, upgrade to a new phone you'll be locked out and cannot access your account unless you have an emergency password or something. Seems like this is the only way to get your acct back.

It would be nice if you could easily transfer everything without getting locked out if you were to upgrade to a new phone, etc...
