Another very strong vote for an app login. Just a simple passcode, anything. I love keeping a journal on EN, but like many posters here, my family uses my laptop, my ipad, and I can't sit there and watch them while they do. It's a HUGE problem that I have to censor my own journal out of this concern. The existing encryption feature is a very poor substitute because there is no notion of global login or decrypt, so you can't search your encrypted entries, for example. And please don't tell me to keep my journal just on one protected device. It defeats the purpose. We love the ability to use a phone OR a laptop wherever we are. And realistically, most of us in families don't have an entirely private device. PLEASE implement this. As others have said, doesn't need to be high-level security, just a simple gate will do.
