**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. Two-step verification can greatly reduce unauthorized access to most accounts by identifying new or unknown computers or devices.

LinkedIn encourages all members to turn on two-step verification. Two methods of verification are available:

- Text (SMS) verification.
- Authenticator app verification (like Microsoft Authenticator). LinkedIn recommends the authenticator app as the preferred two-step verification method.

**How does two-step verification work?**

When LinkedIn does not recognize the device that you're attempting to sign in from, you'll be asked to enter your account password as the first layer of verification and a pin code as the second layer of verification. The pin code will be sent to your phone via SMS or authenticator app, depending on the two-step verification method you selected. If you are logged into LinkedIn on a mobile device and have push notifications enabled, you will receive a push notification on your mobile device with a sign-in security prompt instead of one of the 2FA methods.

**Important**: LinkedIn requires all Recruiter, Talent Hub, Campaign Manager, and Sales Navigator users to turn on two-step verification through their LinkedIn.com accounts in order to access their Recruiter, Talent Hub, Campaign Manager, and Sales Navigator accounts.
