+# Authority Delegation In ABP Commereical
+
+In this post I'll explain a new feature from ABP Commercial 7.2.0: **Authority Delegation**.
+
+## Authority Delegation
+
+Authority Delegation is a way of delegating the responsibility of the current user to a different user(s) for a limited time. Thus, a user can be switched to the delegated user's account and perform actions on their behalf.
+
+> This feature is part of the [Account Pro module](https://commercial.abp.io/modules/Volo.Account.Pro), which is one of the application modules of [ABP Commercial](https://commercial.abp.io/).
+
+### Delegating a new user
+
+After logging into the application, you can see the `Authority Delegation` menu item under the user menu. When you click the menu, a modal will open and in the first tab of the modal, you will be seeing the list of delegated users.

+
+You can click the `Delegate New User` button to delegate a new user:

+
+* You can specify a time range to ensure the delegation is only available within the time range.
+* You can make multiple delegates to the same user and set different delegate time ranges.
+
+> The delegation has three states: `Expired`, `Active`, and `Future`. These states are set automatically by checking the specified time interval.
+
+### My delegated users
+
+A list of users who delegated me to login on behalf of them can be seen in the figure:

+
+You can click the `Login` button to login to the application as a delegated user and go back to your account by clicking on the `Back to my account` icon.

+
+> The **Authority Delegation** feature uses the [impersonation system](https://docs.abp.io/en/commercial/latest/modules/account/impersonation) internally.
