Berbix is asking you to perform some random action in order to ensure that you are a real person and not someone trying to steal your identity.

Identity fraud is a real problem that can happen to anyone. Often very sensitive information will be provided if you’re able to validate your identity with a company. We want to ensure that you and only you are able to complete this identity validation. One common pattern that a fraudster may attempt to steal your identity is to use a photo of you in order to satisfy a verification flow. By asking you to perform a random action, Berbix can ensure that it’s a human who is completing the flow and not a fraudster with a photo.
