does not work well on iphone
I can use it to log into apps on my iphone, but I cannot (and I keep trying) register with an app using 1password. This means I can only ever register to a new website on my computer. The 1password guide is not helpful as the key symbol does not exist when attempting with an app. It is, there when I need to enter a password and this works, but when I need to create a password, it is not there. Broadly speaking, it is otherwise very useful and the UI interface was better than others I have tried. None are perfect - I suspect it is a tricky area to get to work across all browsers/apps, etc. I do have to "clean up" once in a while to delete passwords that have somehow not synced. I use it to separate work and personal passwords which is useful. I could probably learn to use it better.
