Editor to share with you how to make the sudo password session timeout longer in Linux, I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it together.

In Ubuntu and its derivatives such as Linux Mint or any other Ubuntu-based distribution, when you execute the sudo command, it will prompt you for an administrative password.

By default, the password will remain for 15 minutes after the sudo command is executed *, so you don't need to type a password for each sudo command.

If, for some reason, you think 15 minutes is too long or too short, you can make a simple adjustment in the sudoers file.

To set the sudo password timeout value, use the passwd_timeout parameter. First open the / etc/sudoers file with root privileges using the sudo and visudo commands, as follows:

$sudo visudo

Then add the following default value, which means that the sudo password prompt will expire 20 minutes after the user uses sudo.

Defaults env_reset,timestamp_timeout=20

Note: you can set the minutes to any time you need, and it will wait until it times out. If you want to pop up the password prompt for each sudo command executed, you can also set the time to 0 or disable the password prompt by setting the value-1 *.

The screenshot below shows the default parameters I set in the / etc/sudoers file.

Timeout for changing sudo password

Press Ctrl + O to save the file, and then use Ctrl + X to exit. Then, use sudo to run the command and wait 2 minutes to check if the password prompt timed out to test that the settings are normal.
