Advantages of registration[edit] User registration and login enables a system to personalize itself. For example, a website might display a welcome banner with the user's name and change its appearance or behavior according to preferences indicated by the user. The system may also allow a logged-in user to send and receive messages and to view and modify personal files and other information.

Disadvantages of registration[edit] Registration necessarily provides more personal information to a system than it would otherwise have. Even if the credentials used are otherwise meaningless, the system can distinguish a logged-in user from other users, and might use this property to store a history of users' actions or activity, possibly without their knowledge or consent. A system could even sell information it has gathered on its users to third parties for advertising or other purposes. Depending on the nature of the system, a user might not have any way of knowing for certain exactly what information is stored, how it is used, and with whom, if anyone, it is shared. The subject of systems' transparency in this regard is one of ongoing debate. Registration may also be seen as an annoyance or hindrance, especially if it is not inherently necessary or important (for example, in the context of a search engine) or if the system repeatedly prompts users to register. A system's registration process might also be time-consuming or require that the user provide information they might be reluctant to, such as a home address or social security number.[1]
