Can't login with Gmail App/Play Store on tablet; Username/Password OK on desktop web browser I've spent the last 15 or 30 minutes trying to login to the Gmail app and the Play Store on an ASUS TF-101 tablet. During the same time, I've visited a desktop computer, logged out, re-entered the username and password, and logged back in just fine.

Here's a cropped image after attempting to login to Play Store. I'm certain the username and password are correct from testing on the desktop:



The tablet has internet connectivity, and the time is set correctly. I even performed a factory reset and the problem still persists.

A few questions:


Any ideas why I've wasted 1/2 hour trying to login using this tablet?
How do I login into Gmail App and Play Store using Gmail credentials on an ASUS TF-101 tablet?
Why am I being forced to use a password mask created for a 1960s teletype terminal in 2014? I certify that no one is standing behind me.
How do I remove the password mask so I can actually see what's being entered?

Did u set 2 step verification to your Gmail account? If yes then you need to set Application Specific Password to your account. 


Login to your Gmail from Desktop. 
Goto Settings page. 
Find Authorizing Application &amp; sites page. 
Goto Application Specific Password section 
Set your app name and device and Password, then click Ok. 
Now you can login to your app with that new Application Specific Password.
