Option to sign in without Account Key?

@shawnlcl This would be nearly impossible to do and very hard to do well, since the account key is just as important as your master password and without either your data cannot be decrypted. So I don't see AgileBits providing it any time soon. I say nearly because there are mathematical ways of requiring 2 of 3 parts of something for decryption but it adds complexity and thus is hard to do well.

Accessing your account on a non-trusted system would expose all account contents to being stored or used by that system, so it's not a great idea anyway, regardless of what login information you use. Security does prevent some convenience sometimes...syncing to mobile phone is how I get around that most of the time.
