The fastest way depends on your device type

Changing your lock screen takes two to five minutes and works differently on each operating system. On Windows 11, you go through Settings > Personalization > Lock screen. On Mac, it is System Settings > Lock Screen. iPhone users swipe up from the bottom and tap the plus icon to add a new lock screen, then customize it. Android varies by manufacturer, but most let you long-press the lock screen directly to edit it.

The steps below cover the most common devices. If your phone or computer is older, some menu names may differ slightly, but the general path — Settings, then Personalization or Display, then Lock Screen — stays the same across most versions released in the last five years.

Key Takeaways

  • Windows 11 lock screens change in Settings > Personalization > Lock screen, where you can pick a photo, slideshow, or Windows Spotlight.
  • Mac users go to System Settings > Lock Screen and can choose a static image or dynamic wallpaper.
  • iPhone lets you create multiple lock screens by swiping up from the bottom and tapping the plus icon, then selecting a photo or style.
  • Android lock screens are customized by long-pressing the lock screen itself on most phones, though Samsung and Google Pixel have slightly different paths.
  • All methods let you change the image, add widgets or shortcuts, and adjust text color and clock style without affecting your home screen.

Windows 11: Changing your lock screen image

Open Settings by pressing Windows key + I, or click the Start menu and select Settings. Navigate to Personalization on the left sidebar, then click Lock screen. You will see three options under "Personalize your lock screen": Picture, Slideshow, or Windows Spotlight.

If you choose Picture, click Browse and select an image from your computer. Windows will resize it to fit. If you choose Slideshow, click Browse and select a folder containing multiple images — Windows will cycle through them each time you lock your device. Windows Spotlight pulls images from Microsoft's collection and changes them automatically.

Below those options, you can toggle "Get fun facts, tips, and more on your lock screen" on or off. You can also click "Timeout settings" to control how long your screen stays on before locking. These changes take effect when ready the next time you lock your device.

Mac: Setting a lock screen background

Click the Apple menu in the top-left corner and select System Settings. Click Lock Screen in the sidebar. You will see a preview of your current lock screen at the top.

Click the dropdown menu under "Background" and choose from Dynamic, Classic, or a photo. If you pick a photo, click Browse and select an image from your computer. You can also drag a photo directly from Finder into the preview area. Mac will automatically adjust the image to fit the lock screen.

Below the background option, you can customize the clock style, date format, and whether notifications appear on the lock screen. You can also set a message to display on the lock screen by clicking the message field. All changes save when ready.

iPhone: Creating and customizing lock screens

Swipe up from the bottom of your home screen to open the lock screen customization menu. Tap the plus icon (+) in the bottom-left corner. You will see options to create a new lock screen from scratch or duplicate an existing one.

Tap "Create a New Lock Screen" and choose a style: Photo, Color, Weather, Astronomy, or Gradient. If you pick Photo, select an image from your library or take a new one. Once you have chosen a base, you can customize the clock font, color, and size by tapping the clock itself. You can also add widgets by tapping the area below the clock and selecting from available options like weather, calendar, or reminders.

After customizing, tap Set as Lock Screen or Set as Both to explore it to your lock screen and home screen. You can create multiple lock screens and swipe between them on your actual lock screen. To delete one, swipe left on it in the customization menu and tap Delete.

Android: Customizing your lock screen

Long-press your lock screen until a menu appears at the bottom. Tap Customize or Wallpaper (the exact label depends on your phone's manufacturer). You will see options to change the background image, add widgets, and adjust clock style.

To change the image, tap Wallpaper and select a photo from your gallery or from the built-in collection. To add widgets, tap Widgets and choose from options like weather, calendar, or news. You can also customize the clock by tapping Clock style and picking from available designs.

On Google Pixel phones, the menu is labeled "Customize lock screen" and includes a dedicated section for adding shortcuts at the bottom. On Samsung devices, go to Settings > Display > Lock screen and choose from Wallpaper, Clock style, and Widgets. Changes take effect when ready.

Changing lock screen without changing your home screen

On all devices, your lock screen and home screen are separate. Changing one does not affect the other. Windows, Mac, and Android all keep them independent by default. On iPhone, when you customize a lock screen, you have the option to explore it to the lock screen only or to both the lock screen and home screen — choose "Set as Lock Screen" if you want to keep your home screen unchanged.

This separation means you can have a professional photo on your lock screen and a different image or layout on your home screen. You can also create multiple lock screens on iPhone and Android and switch between them without touching your home screen at all.

Troubleshooting common lock screen problems

If your image appears stretched or cropped, the resolution may be too small. Lock screens work best with images at least 1920 × 1080 pixels on Windows and Mac, and 1080 × 1920 on phones. If the menu does not appear when you long-press on Android, try holding your finger on an empty area of the lock screen rather than on the clock or widgets.

If changes do not take effect, lock and unlock your device once. On iPhone, if the customization menu does not open, make sure you are swiping from the very bottom of the screen. On Windows, if Settings does not open with Windows key + I, try right-clicking the Start menu and selecting Settings instead.

Frequently Asked Questions

Can I use a video or animated GIF as my lock screen?

Windows and Mac do not support video or GIF lock screens natively. Android does not either, though some third-party lock screen apps offer this feature. iPhone does not support animated lock screens, but you can use a dynamic wallpaper, which is a short looping animation provided by Apple.

Will changing my lock screen affect my passwords or security settings?

No. Changing the image or appearance of your lock screen does not change your PIN, password, or biometric security. Your device remains locked the same way — you still need to enter your password or use your fingerprint or face to unlock it.

Can I set different lock screens for different times of day?

iPhone allows you to create multiple lock screens and set them to appear at specific times using Focus modes. Android does not have a built-in scheduling feature, but some third-party lock screen apps offer it. Windows and Mac do not support time-based lock screen changes.

What happens to my lock screen if I update my operating system?

Your custom lock screen usually stays in place after an update. However, if you are updating to a major new version, some customizations may reset to defaults. It is a good idea to note your settings before a major update so you can reapply them if needed.
