Let me start by saying that I love the LastPass idea. I use it on my desktop browser every day and it makes me a safer and faster internet user. I have also installed the LastPass app on my iPad and have been using it for two years. It does its main job of keeping my passwords secure, however they are not always that easy to get to.
Have to leave Safari
To start off with, I often end up using Safari while my iPad just from other apps using it to open a browser window. LastPass does not work from inside the Safari iPad browser. Inevitably, I will go to a webpage with Safari that wants my login credentials. Often it is a specific page within a secured website, so I have to copy the URL, open LastPass, and paste it in. Argh! If LastPass could function as a plug in like it does on the desktop, I could just enter my password into the Safari plugin and be on my merry way. But that is just not the case.
Old tabs are useless
Once inside LastPass, things get a bit better. However, you have to remember to log in first. If you open it and access a tab that is still open from your last session, you can’t use LastPass to fill any passwords. Worse, you will have to log into LastPass, which is understandable, but then you have to close and reopen all of the tabs that you want to use. Since most of us visit the same sites over and over, this can be quite annoying.
In summary, if you use the LastPass app by going to it first and logging in before you do anything, you will have a pretty good experience. However, in the course of using your iPad, you often run into apps from other apps and this experience is not quite smooth. If you want to keep your password secure though, LastPass is worth it. You just have to learn to work around its shortcomings.
