The problem with creating a unique password for every service you use is that it becomes increasingly hard to remember many passwords. It is hence important to have a unique password for every new registration on a new website. You can use the same password across many websites, but in case one of your passwords is compromised, your accounts on all websites can be compromised. As such, every new registration requires you to remember a new password. While many websites provide registration through Gmail and Facebook for convenience, it is in your best interest to maintain separate registration for individual websites. Social media platforms, forums, email providers, shopping websites, and many other platforms require user registration to log in and access services. User registration on websites has become more common to avail services and to have a seamless browsing experience.
