Use ASP or unlock Captcha
If you’ve turned on 2-Step Verification and are trying to sign in to your Google Account through a device, mobile app or desktop app, you’ll need to enter an App Password.
You’ll need to create a different App Password for each device or application you’d like to use with your Google Account. For example, if you access your Google Account on both your iPhone and the Picasa desktop application, you’ll need need to create an App Password for each.
If you’re having trouble using an App Password on your phone:
- Go to https://accounts.google.com/DisplayUnlockCaptcha on your phone's browser.
- Enter your username and password, then type the letters on the screen.
- Go back to the application you're trying to access and enter your App Password.
