One of my very favorites these days is called Dashlane. It aggregates existing passwords – and will even create one for you that you don’t even need to know. You remember a master password but that’s it. When David Pogue of the New York Times technology column recommends anything that you just have to do – and he produced a one minute video to that effect – I listened. It saves a huge amount of time – and once the program is installed it allows you to add as you go. Simple and effective.
