Manage the lock settings on your Samsung Chromebook

From your Chromebook's desktop, select the Status tray icon in the bottom right corner. Select the Settings icon.

Under the Connected devices section, check to see if you have a phone added.

If you haven't added a phone, select Set up, and then follow the on-screen instructions to complete the connection.

When a phone is connected to the Chromebook, Smart Lock should turn on by itself. However, you can double check by selecting the connected phone's name and selecting the switch next to Smart Lock to turn it on.

Next, you'll need to turn on another important setting. Select the Right arrow next to Smart Lock.

Choose the option that says Unlock device and sign into Google Account. Enter your Google account password, and then select Confirm.

Next, sign out of your account on your Chromebook. To do this, select the Status tray, and then select Sign out.

On the login page, enter your Google account password, and then press Enter. The next time you need to sign in to your Chromebook, Smart Lock should unlock the computer automatically. Please see the next section for more details.
