Two-step verification (2FA) is a type of Multi-Factor Authentication (MFA) that requires a person to use more than one form of verification to access an account, usually by "knowing something" such as a password and by "having something" such as a mobile device. 

When LinkedIn does not recognize the device that you're attempting to use to sign in to your Recruiter or Talent Hub account, you'll be asked to enter your LinkedIn.com account password as the first layer of verification and a pin code as the second step of verification. The pin code will be sent to your phone via text message (SMS) or authenticator app, depending on the two-step verification method you selected:

• Text (SMS): You’ll need a phone capable of receiving SMS (text) messages. The phone number you enter to turn on two-step verification won’t appear on your LinkedIn profile. Note: Carrier charges may apply.
• Authenticator App: This method uses an app-based authentication code. You’ll need a phone compatible with an authenticator app, such as Microsoft Authenticator.

If you are logged in to LinkedIn on a mobile device and have push notifications enabled on your device, you will receive a push notification with a sign-in security prompt instead of one of the pin code methods. See Sign-in security prompt overview for more information about the sign-in security prompt push notification.

Two-step verification reduces unauthorized access to sensitive information such as InMail, seat assignments, and job postings.
