Of course, if you think the time is too short or you are tired of entering the password, you can change the default timeout time of sudo as follows:

Sudo shortdo

Find the following line

Defaults env_reset

Change this behavior as follows

Defaults env_reset, timestamp_timeout = x

X represents the time. You can set it to 10 or 30, indicating 10 minutes or half an hour.

You can also set it to-1, so that you will remember the password before logging out or exiting terminal. In this case, you can run the following command to forcibly exit sudo for security considerations.
