Key Point

Safely Protects Information from Security Threats

Protection of User Data

Abnormal User Blocking

The administrator is able to manage users by registering users who are using old version of the app or who are performing abnormal operations on a blacklist. If an abnormal user attempts authentication again, the risk of leaking information can be prevented by applying various to policies, such as reauthentication or blocking.
