Steve Gibson and Leo Laporte talked in detail about what happened to Mat on their Security Now podcast last week. It was a perfect storm of failure by Amazon, Apple, and Mat. Worth a listen if you're curious what happened.
Earlier this year they also reviewed some password managers for iOS but some of them have Mac/PC/Android versions as well. Sadly they didn't really talk about 1Password. He did mention an episode or two later that he looked into 1PW and after exchanging emails with the devs was pretty impressed.
