Application passwords are useful if you wish to use an application which does not support 2-Step verification.

  1. Visit https://myaccount.google.com/ and click on "Security".
  2. Scroll down to "Signing in to Google", click on "App passwords".
  3. If prompted, verify your identity.
  4. Choose a service and the type of device you wish to use. Click "Generate".
  5. Use the generated password for your application. Note that once you click "Done", you will not be able to access the app password again.
