For as long as I had an Android phone, I've always used Pocket as my password manager. It's been pretty reliable, easy enough to use, and just leverages my Dropbox account for database backup. It protects my passwords with a master password.
The only problem I had with it is it being only Android supported. The last update it had was back from May 2013. That's almost four years ago. It still works pretty well but I am at the point that I need to pull up passwords on the Mac or Windows and I don't and/or can't grab my phone so I needed cross platform support.
