For security or to prevent certain users from accessing sensitive data, you can create a password to lock your Google Chrome browser on a Windows computer or Mac. Once locked, Google Chrome will need your Google Account password in order to use it. Keep in mind that you cannot lock the mobile app in this way.
Steps

Step 1. Open Google Chrome

The Chrome app icon looks like a red, yellow, green, and blue sphere.

Step 2. Click on your name
It's the small tab at the top right of the browser window.

Step 3. Select Manage Users
This option is at the bottom of the drop-down menu and opens a new window.

Step 4. Choose Add Person
This is the option at the bottom right of the window that has just opened.

Step 5. Enter a name
Type the name you want to give to the new account in the text field at the top of the window.

Step 6. Activate account supervision
Click the box to the left of Supervise this person to monitor and view the websites they visit from your Google Account at the bottom of the window.
You can clear the Create desktop shortcut for this user check box

Step 7. Pull down the Select an account menu
This menu is at the bottom of the window and allows you to display the accounts available on Google Chrome.

Step 8. Select your Google account
Click the email address associated with the account you use to sign in to Chrome.

Step 9. Click Save
It's the blue button at the bottom right of the window. Click on it to create a second profile.
It may take up to a minute to create the profile

Step 10. Select OK, understand
This gray button is at the bottom of the window. Do not click Browse as [NAME], because you should not use the supervised account.

Step 11. Click your name again
Your name is at the top right of the window and opens a drop-down menu.

Step 12. Choose Close and Enable Child Lock
You will see this option at the bottom of the drop-down menu. Click on it to lock Chrome with a password and then close the browser window.
You can sign in to Chrome again by opening the browser, selecting your account, and then entering your Google account password
Advice
- Chrome will remember your open tabs. When you unlock it, the tabs should still be open.
- Choose a secure password. A short or one-word password will be easy to crack.
- Email accounts that work with Gmail, but end with a different extension (eg ".edu") or have different domain names (eg "wikihow") will not allow you to lock your browser.
