To verify that you are a human, press and hold a specific code reference. This step is necessary to prevent automated scripts from pretending to be legitimate users.
The verification process involves entering the provided reference ID into a system or using it in conjunction with another form of verification. Once confirmed, this ensures that only genuine users can access certain features or complete tasks online.
If you’re unable to verify your humanity, don’t worry – there are many alternative methods and resources available to help you along the way.
