When you first set up your new Mac or complete a clean installation of a new version of macOS, you’ll first be asked to create a user account. This account is set by default to log in automatically when your computer starts up. While this may be a convenience if you’re the only one using your computer, if you bring your Mac with you outside the house it can pose a serious security risk: anyone who has your Mac can access your files simply by starting it up.Luckily, it’s possible to change this. You can tell your Mac to display a login screen when it starts up.
Disable automatic login on Mac
- From the Apple menu in the top left of your menu bar, open System Preferences, and go to Users & Groups. Select Login Options from the list on the left.
- Click the padlock icon and enter your password to make changes.
- From here, you’ll see a menu that allows you to choose which user logs in automatically at startup. You can choose to have a different user log in automatically or select Off to turn off automatic login.
There is also another way of changing your automatic login preferences. Here’s how:
Open System Preferences and go to Security & Privacy.
From the General tab, you can select Disable Automatic Login.
