This added level of security is almost necessary now a days with all the logging in we do from various places. Had Hotmail used something like this I would not have had to delete my account. it doesn't bother you all the time either. If you are logging in from home or any safe computer, just tell it to remember the authentication for 30 days and you are good for a month. Well planned and works very smoothly. Set this up via your Google account settings/other settings/2 step security.

Doesn't even work I have 2-step enabled, for years now might I add, and it is telling me that I don't have it enabled. My computer has logged me out and is requesting I sign back in but I can't because I need this app to give me a code. Now I have to go through Google and wait 3-5 days to recover my account. Don't bother downloading this app, it's a piece if crap and doesn't even work.

More trouble than it's worth. I can no longer access the google servers with this thing, so now I'm unable to do anything with it. I can't even disable anything protected by it without a code it generates, so I'm just screwed. Thanks, guys.

Works but is very outdated. No backup options or material design. Very disappointed.

??? I didn't have two step turned on at the time of installing this app so it told me to turn that on from computer first. I did that. Re-signed in to my phone with google, a few reboots, this app still says same for that particular account. Turn two step on first.

Good, but better alternatives exist.
