People aren't the only identities accessing systems.
Applications and services need permissions too.
A service account shouldn't have administrator access just because it's convenient.
Give it only what it needs.

IP address
Subnet
Gateway

Servers, devices, domains, licenses and cloud resources all need ownership and purpose.
Good inventory is part of good IT operations.

Authorization asks: What are you allowed to do?
A successful login doesn't automatically mean the user has permission to perform an action.

Creating a user account is easy.
The bigger responsibility is managing that access as the person's role changes and eventually removing it when it is no longer needed.
