I've been reading your blog about the latest security changes, and I applaud your efforts to keep up to date with current cryptography. However, I'm reading that you're removing the 4-digit Unlock Code from 1Password Pro on the iPhone, due to weak security and general confusion from customers.
I use a very strong master password, which is super annoying to type on the iPhone. It requires switching between several keyboards multiple times, and my fat fingers can't get it right sometimes and I have to start over. Please don't force me to do this, as it'll actually diminish security by encouraging me to choose a simpler password due to the iPhone's limitations.
About 90% of the time I use the iPhone 1Password app, it's to find forum passwords, check my kids' grades, log in to order ballet tickets or pizza, and other minor things of this nature. I use the 4-digit low security password for these items because it's convenient and the repercussions of having these cracked are very minor. In other words, I'm using the Unlock Code for its designed purpose.
Can you make the Unlock Code an option instead? I'd even argue to put it on the iPad app as well. The alternative is that I, arguably an ideal informed user, will feel encouraged to choose a less secure master password.
Also, can you please let me know which version of the iPhone app gets rid of the Unlock Code, so that I can avoid applying that update as long as possible?
Thanks for listening!
