My client isn't accepting my username and password

If you're repeatedly prompted for your username and password, or if you're getting an 'invalid credentials' or 'web login required' error, make sure your password is correct. Keep in mind that passwords are case-sensitive.

If you’re sure your password is correct, you can try these troubleshooting tips:

  • Sign in to your account from the web version of Gmail at https://mail.google.com. Afterwards try accessing your messages in your mail app again.
  • If you're still having problems, visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password. If necessary, enter the letters in the distorted picture.
  • Your mail app might not support the latest security standards. Learn how to allow less secure apps access to your account.
  • Make sure your mail app isn't set to check for new email too frequently. If your mail app checks for new messages more than once every 10 minutes, the app’s access to your account could be blocked.
  • Try changing your password according to our tips on creating a strong password.
