I've been using LastPass for a few months and have loved it, but maybe I'll consider switching to 1Password.
However, can I just rant for a second about how these security assessments and blog posts fold out? The beginning of my career was spent thinking I was going to go into this field (one of my degrees is in Information Assurance) and the #1 thing that persuaded me to switch to building software instead was the attitude and approach of the security field.
If it's not 100% secure and we all agree that it's the 100% best way to do something, it's the end of the world and anyone using LastPass is an idiot who will have all of their passwords hacked and their life ruined. (Remember when the draft for client side storage was announced? You would have thought armageddon was upon us based on the reaction of the security industry.)
Big picture here -- most people re-use a short, simple password on all of their sites. Using a password manager, even one with a few things that it can and should improve, is a HUGE step in consumer behavior. Bickering amongst ourselves and boasting for crapping on someone's company is not the right approach to increasing our entire society's security stance.
Want to actually help?
1. Create more resources to help consumers pick, use, and adopt a password manager with super simple setup process. Even the current methods that all password managers use of generating, saving, and autofilling passwords are too complex and cumbersome for the average consumer. Heck, even MFA is seen as a huge waste of time and barrier to logging into people's accounts by the majority of people right now.
2. Create more resource to educate developers of these services, helping them to see what they should do and how they should do it, not bragging about your ability to tear down a service they spent hours slaving over. Get over yourself and actually help society. (https://www.owasp.org/index.php/OWASP_Guide_Project is a great example of this)
Looking for an example? Apple's iTouch. Yes -- it's not the most secure option. People leave their fingerprints all over the place and they can be lifted and used to unlock a phone. But look at the other option -- using no passcode, or a 4 digit passcode that's easy to guess or look over a shoulder. Is it the most secure option? No. Does it raise the level of security for our society as a whole by providing a realistic security barrier that the average consumer can use? Yes.
