# Change Password

To change the password for user presence within the CredentialServicesKit framework, developers can call the `changePassword(oldPassword: String, newPassword: String, completion: @escaping VIDAResultBlock)` method. This method allows for the modification of the existing password by providing the current password (`oldPassword`) and the desired new password (`newPassword`).

It's important to note that when the password is changed, the biometrics feature will be disabled. This means that users will need to re-enable biometric authentication if desired.
