Cons
Con Not open source (free/libre)
This application is proprietary, and thus cannot be modified, freely distributed, or trusted to be secure.
Con Inability to fill password sometimes
You have to fill twice to make it work.
Con Default is subscription model
It's really hard to find out how to obtain a full license.
Con Support sucks
Support does sometimes does not read requests thoroughly, and offers ham-baked or non-workable sulutions.
Con Unintuitive and slow responding UI
A hot mess of desktop applications and browser plugins that are supposed to work together, but don't always do. Browser plugins frequently become unresponsive and are very basic in comparison to other solutions.
Con Lack of Google Drive sync
Only icloud, wifi and Dropbox support.
Con Tough/impossible to get on Chromebook
Con Does not auto-fill and generate passwords in Microsoft Edge for Windows 10
The 1Password Edge extension doesn't work as well as in other browsers, as it can't auto-fill and generate passwords. Only LastPass seems to have a fully-functional browser plugin for the Edge browser at this time.
Con Unreasonably high price
It has a high monthly subscription price.
Con Iridium is currently on hold
The current build includes a bug which seems to break youtube functionality. However after a bit of searching, a solution can be found. Posted here to help others who might be debugging all their extensions for youtube not loading videos.
The solution for many seems to be to keep the autoplay function within Iridium settings ON.
Now your videos will most likely load and play again like they should.
