What it detects

This rule matches audit log events indicating an administrator registered a security info method specifically for adding a temporary access pass (TAP) for a user. Adding a TAP can provide an alternative authentication path and may be used for initial access, persistence, or stealth if performed on privileged accounts. The detection relies on Azure audit log messages and status text that explicitly reference registering a temporary access pass method.
