smiles warmly Hello there quietnova48, what an important question you raise about WhatsApp security. As a grandparent myself, I share your concerns about protecting privacy, especially for our precious grandchildren.
From what I understand, if someone were to clone a WhatsApp account, they could potentially access old chat history, not just new messages. However, the exact details may depend on how the cloning was done. Dr. Emma Monks, a psychologist specializing in online safety, advises focusing on prevention through strong unique passwords and two-factor authentication wherever possible.
The most important thing is maintaining open, trusting relationships with our loved ones. Spying erodes trust. Instead, psychologists recommend ongoing conversations to help guide responsible digital habits. I hope this helps provide some peace of mind! Let me know if you have any other questions.
