- When an application is started for the first time, avoid frequently displaying dialog boxes to request multiple permissions. Allow the application to apply for the permission only when it needs to use the corresponding service function.
- If a user rejects to grant a permission, the user can still use functions irrelevant to this permission and can register and access the application.
- Provide no more message if a user rejects the authorization required by a function. Provide onscreen instructions to direct the user to grant the permission in **Settings** if the user triggers this function again or needs to use this function.
- All the permissions for applications must come from the [Application Permission List](permission-list.md). Custom permissions are not allowed currently.

### Verifying a Permission
To protect sensitive data and eliminate security threats on core abilities, you can use the permissions in the [Application Permission List](permission-list.md) to protect an API from unauthorized calling. Each time before the API is called, a verification is performed to check whether the caller has the required permission.
The API can be called only after the permission verification is successful.

The user_grant permission list must also be presented on the details page of each application in the application market.
### Permission Groups and Permissions
To minimize the number of pop-up permission windows and optimize interaction experience, the logically related user_grant permissions are combined to form multiple permission groups.
The permissions of the same permission group are displayed in the same dialog box for user authorization. A permission in a permission group is called a sub-permission of the group.
The relationship between a permission group and its permissions is not fixed. The permission group to which a permission belongs may change. For details about the permission groups supported by the system, see [Application Permission Group List](permission-group-list.md).

- To check whether a user has granted a permission to your application, use [checkAccessToken()](../reference/apis/js-apis-abilityAccessCtrl.md#checkaccesstoken9). This API returns [PERMISSION_GRANTED](../reference/apis/js-apis-abilityAccessCtrl.md) or [PERMISSION_DENIED](../reference/apis/js-apis-abilityAccessCtrl.md).

- Users must be able to understand and control the authorization of user_grant permissions. For a user_grant permission, the application must proactively call an API to dynamically request user authorization. Then, the system displays a dialog box asking the user to grant the permission. The user then determines whether to grant the permission.
- The user may revoke the permission authorization at any time. Therefore, each time before an API associated with a user_grant permission is called, the application must check whether the permission is available.

The HUKS operates data based on key sessions. The general process is as follows:
1. (Mandatory) Use [huks.initSession()](../reference/apis/js-apis-huks.md#huksinitsession9) to initialize a key session.
You need to pass in the key alias and key operation parameters to initialize a key session, and obtain the session handle. The key operation parameters must contain the parameters required by the cipher algorithm, including the cipher algorithm, key size, key purpose, working mode, padding mode, hash mode, IV, nonce, and AAD. If access control is set for the key, other parameters are required. For details, see [Key Access Control](#key-access-control).

### Refined User Identity Authentication
As an extension of the Key Access Control, the refined access control allows secondary user identity authentication (biometric authentication and lock screen password) to be performed for key access in one or more scenarios, such as encryption, decryption, signing, signature verification, key agreement, and key derivation. For example, a service needs to use a HUKS key to encrypt the account password information. In this scenario, identity authentication is not required in encryption but required in decryption. To achieve this purpose, you can use the refined user identity authentication feature provided by the HUKS.
