  2. Select the app and device for which you want to generate the app password.
  3. Select App > Mail

  3. Click save changes

What is the 2-step authentication & how do I enable it?

2-Step Verification (also known as two-factor authentication), is a way to add an extra layer of security to your account in case your password and log in details get stolen. The 2-step verification also lets you add devices and applications where you want to link your Google account.

After you set up 2-Step Verification, you’ll sign in to your account with two steps using:

  • Something you know, like your password
  • Something you have, like your phone
