How to Add User to Sudoers in Debian 12

October 2, 2024 by Jeff Wilson

Sudo (superuser do) is a command utility allowing trusted users to run commands as root. It is necessary to run a program requiring root access. Only certain users in the sudo/wheel group can do it. If an unauthorized user attempts to run a command, sudo will notify the administrator via email. By default, this warning notification is saved to the root account. Any user running the command will be prompted for a password. Once authenticated, sudo will create a timestamp for that user. From then on, the user can execute commands for five minutes. Once five minutes have passed, the user will be prompted for a password. If you need to overwrite this grace period, you can do so by changing the settings in the /etc/sudoers file. In this article, we will show you how to add user to sudoers in Debian 12 in a step-by-step guide.
