# 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:                                                                               ![](/files/hdw20qP54NrNj0ycrzd6)  ![](/files/gbntyGZ7mJfz2pxoAj0d)
  * 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.
