How to change the time for which the terminal remembers the sudo password?

Question

linux

After entering the password, due to the execution of the command with sudo, the system/terminal remembers the password for some time and does not ask for it again. According to my observations, maybe 30 minutes. After that, I believe for protection purposes that the user may forget that the commands are from sudo (or is there another reason?), the password is asked again.
How to set this time?
