This 2-step verification only works for the Gmail Web site. You must verify every other application and device that you normally use to access your Gmail, including Outlook and your phone’s email client. To do this, on the application-specific passwords page, enter a name for the kind of application you wish to verify.
Click Generate Password. A password appears in a yellow box. Use this password in place of your normal password when logging in from the application. You should only need to do this once.
This added layer of security is both a blessing and a curse. Sure, it does make it a bit harder for would-be spammers and scammers to gain access to a Gmail account, but it can also be very annoying to verify each and every computer you access every month.
Luckily, Google is giving us the choice of whether or not to use this level of security. Use your own discretion when deciding if 2-level security is right for you.
