You can use your PIN to create, delete, or edit profiles. If you forget your PIN, you can reset it by answering the 'Best friend' security question. After three failed attempts, the current PIN will be deleted, and you will be prompted to create a new one by returning to the profiles page. But first, you will be redirected to the login page.
The primary purpose of a PIN is to ensure that children cannot delete, create, or modify their profiles without parental authorization. This feature provides parents with full control over their children's accounts, allowing them to review chat history or manage account-related activities as needed.
