Google has announced that from 9th November you will likely not be able to access your email without your smartphone nearby.
This is after the firm announced that the 2 step verification will now be default to all its millions of users globally.
Google originally introduced its effort to auto-enroll users into the two-factor authentication system back in May. But at the time, the company simply said the plan would be implemented “soon” without elaborating.
“After you enter your password, you’ll complete a second step on your phone. Keep your phone nearby when you sign in. 2-Step Verification will be turned on automatically on November 9. You can turn this on sooner if you want — your account is all set.” Read a statement by Google to its users

However, a two-factor authentication can stymie an intrusion attempt by requiring anyone logging in to provide a second mode of user verification, which usually involves generating a one-time passcode on the account holder’s smartphone. The passcode then has to be entered into the login window.
In Google’s case, the company will issue a prompt to the account holder’s smartphone after the correct password is successfully entered. Taping the word “yes” on the prompt will then complete the login process.
