Callback: In the context of secure communications, callback is a method of authenticating a user where a server initiates a new connection to the user’s registered contact information (e.g., phone number or IP address) after receiving a request. This ensures that the access request is indeed coming from a trusted source. This method, though not widely used today due to more advanced techniques, adds an extra layer of security to verify the user’s identity.
