Before You Start

Before you get started, learn about the development process.

• Obtain supported authentication capabilities.

• Initiate a request for user authentication and obtain the authentication result.

• Verify and use the authentication result. For details, see Key Access Control via Secondary Authentication.

• (Optional) Cancel authentication.

• (Optional) Apply custom authentication.

Requesting Permissions

Before developing an application capable of user authentication based on biometric features (such as face and fingerprints), you must apply for the ohos.permission.ACCESS_BIOMETRIC permission.

This permission is a system_grant permission and must be declared in the requestPermissions tag in the module.json5 file. For details, see Declaring Permissions.
