How to fix the two-factor authentication log-in error in Gmail on Android

Can't log in to the Gmail Android app after enabling two-factor authentication option? It's easy to fix!

I'm a fan of being secure, so naturally I decided to turn on two-factor authentication for my Google account. Essentially what this means is that every time you access your Google account from a new computer or other device for the first time you will need to enter a code that is sent to your mobile phone as an SMS (or you can install an app to generate the codes yourself). (You will need to reauthorise devices every 30 days — there's also an option to have the authentication expire early.)

However, I (and a lot of other people judging from a quick Web search) encountered a problem with my Android phone after enabling two-factor authentication: The Gmail app wouldn't let me log in, and I couldn't find any option to get Google to send me an authentication code for the app (the mobile Gmail site still worked fine after obtaining a code).

It turns out the solution is simple. The reason the problem happens is, as Google notes (and as I completely ignored when switching on the two-factor authentication option), not all Google apps are compatible with the system yet. However, Google offers the option of using a browser to generate a special application-specific password.

Simply go to your Google account settings, and select the option to edit your two-factor settings. Then select the option 'Manage application-specific passwords'. This will prompt you two enter a name for the device you're authorising (in my case my HTC Desire HD Android phone). You can then generate a random password that will let you use the Android Gmail app. (You can also revoke access from the same interface.)

Problem solved!

nice write up. i totally gaped this when i enabled the two factor. thanks for the reminder about the unsupported apps for this google feature.



Haven't found how to actually do this for my Android device as a whole. Can't update apps, can't sync... But no way to change the "master" Android password. :-P

Thusday of last week, 8/9/2012, my Google Account was comprimised and I was not able to log on. Error message was that there were no documentation related to that address. I set this account a few months ago and connected to my T-mobile "My Touch" slide phone. I am an affiliate and was starting to begin to set up websites on google..At any case when I sent message to my marketers ......... No google account to relate to. everything was deleted that was related to the account with user, I didn't delete anything. whoever changed it put cantu for email address. Please help me find out what happened. ON my phone I have a download that said that people are checking my profile from 2-9 times in 7 days. I don't know these people except for one of them, and she is one of my marketers. And maybe another one who is my facebook friend. There is a name of Richard Kenney I don't even know who this person is. I need help with google



WHERE can I select the option to edit my two-factor settings?






Thanks a lot buddy :)
