The principle of 1 password is great. However, i find it difficult to get my relatives to use it because of the severe learning slope. The differences between the apps on various platforms make explanations difficult, and the differences between app and extensions is practically impossible to explain. Most relatives use their own local app of 1Password (6, 5 or even 4)...and migrating to the newer version is too much of an effort. People don't have enough time to spend 30-45 minutes to learn the new version, get confused because they are accustomed to the old version and things are different, and give up, trash the new version and go back to what they are accustomed to. (BTW the same reaction explains the persistence of older MS Windows OS.)
