Options

ASupporting accountability
BReducing authentication errors
CPreventing password compromise

Unique user IDs are essential for supporting accountability, which is the ability to trace actions or events to their source.

Reducing authentication errors, preventing password compromise, and supporting Single Sign On (SSO) are all possible benefits of using unique user IDs, but they are not the most important reason for configuring them.
