How to Turn on Two-Factor Authentication for LinkedIn

Two-factor authentication (2FA) is a great security tool, and we always recommend it. Most apps make it pretty easy to turn on 2FA, and LinkedIn is no exception. Here’s how to enable it and make yourself safer.

You can turn on two-factor authentication from either the LinkedIn website or the mobile app, but either way, you’ll need to be logged in to your LinkedIn account. Go ahead and do this first.

Turn on Two-Factor Authentication from the LinkedIn Website

Click on your avatar in the top-right corner of the LinkedIn website. In the menu that opens, click the “Settings & Privacy” option.

Click on the Account tab, scroll down to the “Two-Step Verification” section, and then click the “Change” link.

The section will expand. Click the “Turn On” button.

You can choose whether to use an authenticator app to generate a code for you or to receive SMS (text) messages with the code. We strongly recommend using an authenticator app as it’s more secure, but two-factor authentication using SMS is still much safer than not using two-factor authentication at all.

Choose your method—we’re going to use an authenticator app—and then click the “Continue” button.

Enter your password in the prompt that appears and then click “Done.”

The instructions for adding an account to your authenticator app are displayed. Add a new account in your authenticator app, scan the QR code using your phone’s camera, and once the account is created, enter the six-digit code from the authenticator app into the text box in LinkedIn and click “Continue.”

Two-factor authentication is now turned on. Click on “Recovery Codes” to display the backup codes, so you can still get in if you ever lose your phone.

Click “Copy Codes” and save them somewhere secure. You’ll need them to get into your LinkedIn account if you ever lose or wipe your phone.

Now that you’ve turned on two-factor authentication, you’ll need to log in again through any other devices you use, such as your phone.

Turn on Two-Factor Authentication in the LinkedIn App

Turning on two-factor authentication in the mobile app is the same on the iPhone, iPad, and Android. Open the app and tap your profile picture.

Then select the “View Profile” link.

Tap on the Settings gear in the top-right corner.

Open the “Privacy” tab, scroll down, and then tap “Two-Step Verification.”

Select the “Set Up” button.

The instructions for adding an account to your authenticator app are displayed. Add a new account in your authenticator app and then tap “Continue.”

Enter the six-digit code from the authenticator app into the text box in LinkedIn and tap “Verify.”

Two-factor authentication is now turned on. You won’t have to enter the two-factor code on your phone, although you will have to enter it if you access LinkedIn on any other device.

Tap the “Recovery Codes” link to display the backup codes, so you can still get in if you ever lose your phone.

Tap “Copy Codes” and save them somewhere secure. You’ll need them to get into your LinkedIn account if you ever lose or wipe your phone.

Now that you’ve turned on two-factor authentication, you’ll need to log in again on any other devices you own using the two-factor code.
