# Allow Permissions

## **Option 1**

* After creating the passcode, the user uses the passcode for the first time. The app requires the device's permission to use biometrics. 
* Display a popup request for the app to access biometrics:                                                                               ![](https://3885373335-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FX7ySYFWpl8DCdr37E2NT%2Fuploads%2FmH3j71z8Ig5re4D294y3%2Fimage.png?alt=media\&token=314835a1-1cdd-48ae-b0aa-264049120ab1)  ![](https://3885373335-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FX7ySYFWpl8DCdr37E2NT%2Fuploads%2FsxIOTn86zyud9OtwN9JY%2Fimage.png?alt=media\&token=7bb064bd-4271-400b-820c-175f5ddeea54)
  * If the user allows it, they can use biometrics (Face ID/Fingerprint) for authentication.
  * Otherwise, they can only use a passcode. 
* Note:
  * Depending on how the device supports security, if the device does not have biometric security, the user can only use the passcode. 
  * After granting permission, the next time, the user can use biometrics (Face ID/Fingerprint) or a passcode to authenticate.

## Option 2

* Users can access the device's settings to grant permission to the application.
