Notice: Auto Logout Feature Deployment in COSYS+

To enhance system security and mitigate risks from unattended access, AAT will deploy an Auto Logout feature in COSYS+, effective from 8 Jul 2026. The system will automatically log out after 20 minutes of inactivity, and user can simply re‑login to continue using the system.

Notes:

  • Page navigation alone is not considered user activity.
  • When using multiple browser tabs, only the tab(s) inactive for over 20 minutes will be logged out. Active tabs will remain logged in.

 We appreciate your cooperation and support as we continue to strengthen our cybersecurity measures.
