scanning your face instead of using a password.
Create face ID

2. Scroll down to the Password section and click Add to create a password.
3. Follow the on-screen instructions to create a Personal Identification Number (PIN).
4. Locate the Windows Hello section and click Set up under Face Recognition . Then, click Get Started .
5. Enter the PIN you have set earlier. The camera preview starts.
6. Follow the on-screen instructions to complete the setup.
7. Click Improve Recognition to improve the image so that Windows Hello can recognize you in different
light conditions or when your appearance changes.
Log in with face authentication
1. On the Windows lock screen, select the smiling face icon from the sign-in options.
2. Follow the on-screen instructions and ensure that you are centered and looking directly at the camera.
When the program recognizes your face, it automatically unlocks the screen and signs you in to the
Windows operating system.
Use firewalls and antivirus programs
Your computer might be preinstalled with a firewall program. The firewall protects against computer Internet
security threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy.
A full version of antivirus program is provided with a free 30-day subscription. After 30 days, you must renew
the license to continue receiving the antivirus program updates.
For more information, see the help system of the program.
