I hope you can get something after reading this article. Let's take a look at this "Linux how to customize sudo password session timeout" article.

The sudo command is a permission delegated command, which can grant root permissions to ordinary users. It is very common in practical applications. By default, the sudo command session time is 5 minutes.

To set the sudo password timeout value, use the passwd_timeout parameter.

Edit / etc/sudoers

First open the / etc/sudoers file with root privileges using the sudo and visudo commands, as follows:

$sudo visudo sets timeout time

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 permanently disable the password prompt by setting the value-1.

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

Test timeout

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.
