To secure your Blockchain 2-Step Verification (2FA) is important providing an extra layer of security to your wallet. Actually, when you login into your account, you need both the wallet password plus a one-time passcode (OTP) generated through your selected 2FA reset methods like Google Authenticator, Yubikey, or SMS codes depending on choice.
To enable 2FA Blockchain, go to wallet security center and under the two-step verification section, click on enable and select which option you want to setup.

Step 1: First download the free application from the App Store or Google Play store.

Step 3: Now you will see a QR code which you have to scan with your Google Authenticator App.
Android Users: Android users, open Google Authenticator on your device and click the three dots appearing on the upper right corner and then select “Add an account and scan the bar code.
