Just curious here, do you have a Google account? If so then:
Go to AuthSubTokens and enter your login details to see if your Android device is listed. If your device is listed, it will be shown as an "Android Phone"
Revoke access for the device.
Generate a new password.
At the bottom of the page, you will see an option to "Generate New Application-Specific Password".
Enter any name and click on "Generate Password".
A 16-digit password will be generated.
Enter this new password in your Android device, along with the correct Google ID.
If the "Generate password" option is disabled, you'll need to enable 2-Step Verification.
Follow the 2-Step Verification link to Google, and set up 2-Step Verification.
Depending on your device, you'll receive options from Google to generate a new password and access your Android device using the 2-Step Verification process.
