The Account Protection tab provides options related to Account Protection, such as canceling of the protection and managing trusted clients. To view this tab, click the person-shaped icon at the upper-right of the DSM desktop and select Personal.
If your account becomes protected when a malicious attack occurs, you can cancel the protection yourself.
Once a client successfully logged in, it will be always trusted. If current client is untrusted, you can still reset it as trusted.
All trusted clients of your account are listed.
Select the clients which you want to untrust, and click Untrust.
