Authentication on PayPal by number is done through a process called two-factor authentication. When a user logs into their PayPal account, they are prompted to enter their username and password as the first factor. Then, a unique code is sent to their mobile phone number, which they must enter as the second factor to complete the authentication process. This adds an extra layer of security to the login process, helping to protect the user's account from unauthorized access. **

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet. On the other hand, an antivirus is a software program designed to detect, prevent, and remove malicious software, such as viruses, worms, and Trojan horses, from a computer system. While a firewall focuses on controlling network traffic, an antivirus focuses on identifying and eliminating specific types of malware that may have already infiltrated the system. In summary, a firewall is a network security tool, while an antivirus is a software tool designed to protect individual devices from malware. **
