Turning two factor authentication can put a stop to anyone’s efforts to access anything including Gmail and all other Google services that uses your Google account credentials when logging in because you need more than a password to verify that you are the account owner.
You can enable two factor authentication known as 2FA for your Gmail account on Google’s single settings page, so your new, more secure settings will apply across other Google services like Google Drive and Google+. Google calls it “two-step verification”, but the idea is exactly the same: if signing in requires something you have (like your phone) as well as something you know (your password), then your account has an added layer of protection.
Steps to Turn-on Two Factor Authentication on Gmail:
Two-step verification adds an extra layer of security to your account. Think in terms of withdrawing cash from an ATM — you must insert your card and enter a personal identification number. In the case of a Google account, with two-step verification enabled, you must enter a password and a code that is sent to your phone by call or text, or through an authenticator app on your phone.
It can be very easy & simple to enable two factor authentication security on Gmail by following the discussed steps like LinkedIn Two-Step Verification, Facebook Login approval & Twitter Login verification.
Steps 1: First, Login to your Gmail account as usually do. After that click on your profile picture in the upper-right hand corner and click “My Account”.
Now choose “Sign-in & security” to manage your account access and security settings.
Now Select “2-Step Verification” under “Password & sign-in method”.
At this point, before you make log-in changes to your account, Google may ask you to enter your password and sign in again.
Step 2: Now you can set up two factor authentication. Click “Get started”.
Enter your mobile phone number. You’ll need to be able to receive text messages and/or voice calls at this number. Choose which you’d prefer and click “Next”.
Soon after you click, you should receive a text or call with your code. Enter just the numbers, without the “G-” prefix, and click “Next”.
Now Click “Turn on” to enable two factor authentication for your Google services like Gmail, Google+, Google Drive, Photos etc.
Now you’ll be back at Google’s 2-Step Verification settings page, where you can set up an “alternative” second factor in case you cannot receive texts/calls.
Keep in mind that the general default option of receiving codes via SMS is vulnerable to interception by your telecom and others and is less secure than other available methods.
Google’s Authenticator app is one popular choice: it generates free, one-time passwords and is supported by a range of services, including Facebook, Dropbox, and Microsoft.
Additionally, you’ll want to create app passwords if you access your Gmail on third-party devices or applications like an iPad or iPhone, Thunderbird, or Outlook.
App passwords are for devices and applications that do not support logging in using a one-time verification code. Most of the time, you’ll only have to verify and enter an app password once for each app or device.
