Login to the ChatGPT website. Open chatgpt.com on your web browser and log in with your account using the "Log in" button at the top-right corner of the screen. You can’t change settings without logging in to ChatGPT.
- ChatGPT will set your system’s theme as its default theme. If your PC is in dark mode, you either have to log in to your account or change your system theme.

Click your profile icon. You can see your profile icon, along with your display name if the sidebar is expanded, at the bottom-left corner of your screen. A menu box will show up.
- If you use a mobile browser, tap the two-line button, at the top-left corner of your screen.
3
Click on the Settings option. You can find it next to the Help option in the menu box.

Warnings

Theme settings only apply to the device and platform where you set them. For example, changing the theme on the web won’t affect the mobile app, and changes on Android won’t apply to iOS. You need to adjust the theme separately on each device or platform.^{[2]
