Additionally, managing your own password vault is a lot like managing your own email server. There's advantages but I feel that the disadvantages are substantial. For one, the likelihood that you, one person, are going to do a better job of securing your stuff than a dedicated team is optimistic at best. Keeping your password vault safe is literally this companies full time gig and they have entire teams dedicated to it. Do I think they are infallible? Of course not. I'm not an idiot. But I think they are going to do a better job than me at keeping my stuff safe. I happily will pay for that every month.
The authors point about the 1p web portal is a good one. I don't use it out of similar concerns. Besides that, I really could not be happier with 1p as a password management solution. They have a good track record (no hacks that I am aware of) and I want the company I trust with literally the keys to my kingdom to be profitable and motivated to keep improving.
