    Does the job but is very basic. Could use one trap copy, the ability to generate app passwords for apps that can't work with two factor, support for Windows tablets, ability to retrieve secrets for setting up additional devices.

    This does not install automatically and now nothing works and I get messages saying there is a problem with my Windows Live Account; this thing sucks and I'll now likely have to spend hours trying to fix this. DO NOT INSTALL this piece of junk.

    I had issues about this app because it lacks instructions on what you're looking at and what to do after you inter the code that's given. As I watched the task bar running, I'm thinking its trying to identify my user name and the code I entered. There was no instructions prompting you to close the app because its doing what it supposed to do at that point. I logged into Windows Community to ask questions on what was I supposed to do after that point. And got replies back from the monitors, I shouldn't be using it because I didn't understand what to look for at no fault of my own. I SAY WHEN MAKING A APP LIKE THIS DON'T JUST EXPLAIN WHAT IT DO. ALSO WRITE SOME INSTRUCTIONS ON HOW TO USE IT AFTER YOU INTER YOUR CODE IN. It may help people that don't read minds, like myself understand what to look for in the process of setting up this app!!!

    Hardcoded tile background color of blue is not friendly. 3 stars if fixed. Also some 2fa sites like GitHub cause crashes in the app.
