Persistent "Google sign-in" error, even with correct password

Question

I believe this started after I installed the Google+ app, but there is a constant notification that looks like a warning sign, and it displays this:

Entering the correct password does not dispell it (it's the same password every other Google app uses, and only one is complaining). Also, every Google app still works, each one acts as if I'm still signed in. So where is this coming from, and how can I get rid of it?

Update: I have tried both clearing the data for the Google+ app (which helped for about a half hour) and actually resetting my password and using the new one. Neither worked.

Answer 1

Here is the solution: Login into Gmail, locate Account under the sign-out Name. This takes you to My Account where you click on security. Here you find a section for Application-Specific passwords at the end of the webpage. The issue is explained that: Some applications that work outside a browser aren't yet compatible with 2-step verification and cannot ask for verification codes, for example:

Email programs including Outlook, Apple Mail, or Thunderbird
Older Android smartphones

The root-cause of this problem is that you probably turned on the 2-steps verification without noticing this. So all you have to do is to generate your application specific password and that is it!

Answer 2

I had the same problem. My solution was to uninstall and reinstall Google+ and everything worked fine after that.

Answer 3

This just happened to me as well. I had to change my account password via the website, and then my device accepted the new password.

It only happened with the account I use for Google+, so I think your guess is correct.

Answer 4

I resolved this by signing out of Google+ and then signing back in. This worked on a stock droid x with Gingerbread.

Answer 5

The problem is due to 2 factor authentication.

Go to your Google account on a PC and generate a new Application Specific Password (ASP) (hold off on clicking the button). Enter that into your phone when it asks for a password for Google Sign-in.

If it doesn't work the first time, reboot everything and do it again (remember to hold off on the button until you have entered the 16 character ASP into your phone).

Answer 6

I had a similar problem trying to sign in play store was not authenticating my credentials even though they are correct. I turned off the 2-step verification using the web and worked later on .

Answer 7

Same thing happened since yesterday. It started just after updating the new G+ apps. I thought it was due to my fiddling with 2-step authentication setup, but nope, that wasn't it. Tried reset/reinstall everything. Also tried changing new password. Same thing happened again after installing with the new G+.

I just turned off background sync for G+ (and leave other google apps as-is), and it seems did the trick to stop the error popping up. This is not exactly an answer, but simply a temporary workaround until google comes up with update to fix.

Answer 8

Instead, I opened up the security option of my Gmail account in web. I created a new system-specific password and entered the same. It worked, and I didn't even have to reboot.

Answer 9

I do not have Google+ installed and I reverified my password via the web and I still could not get logged in to my phone.

I ended up disabling two step verification and I was able to login to my phone after that.

I just remembered when I first enabled two step verification I started getting sign on errors when I used voice search.

Answer 10

I had exactly the same thing happen for the 'Play Store' on an Android phone - it would just not accept the correct password! The method that worked for us was to use a computer, access that Google account and disable 2-step verification altogether.

After logging into Google, navigate to https://www.google.com/settings/ -> Security -> 2-step verification -> Edit -> change that to Off.
