How to configure automatic login for Ubuntu (GNOME)

Automatic login in Ubuntu with the GNOME environment removes the need for manual authentication at system startup and can streamline access for single-user systems. It is managed through the Settings application if not set during installation, allowing users to avoid the password prompt. The feature is enabled by modifying underlying display manager settings to auto-load user sessions.

Although automatic login offers convenience, it lowers overall security by granting direct system access. It can be risky in multi-user environments or on machines that store sensitive data, as it bypasses normal authentication safeguards. Carefully consider these factors before deciding to enable this functionality.

Enabling automatic login requires administrative privileges to modify system-wide configurations. Ubuntu uses the GDM display manager, which integrates with the GNOME desktop environment to handle user sessions. Review any potential vulnerabilities and weigh the benefit of quick access against the need for system protection.

1. Open Settings from the application menu or Activities overview.
2. Click on System from the left sidebar.
