TLDR; No. I don’t especially like the look of it. You have to trust a company who is making money out of (hoping) their product is secure. I personally like KeePass ( http://keepass.info ) which works on all my devices and, coupled with a internet sync service (that also leaves you comfortable with the level of security offered), works on all my devices.
So, a friend* of mine asked me yesterday, (following my posting of an article), what I thought of a particular password manager – I obviously wanted to answer her question. I then decided that since I was in for a penny, I might as well be in for a pound and here we are, (hopefully) fixing my response, and posting it in a more readable format.
