# Registration Form

The registration form is a pre-chat form that requires the user to enter specific information before starting the chat.

* You can use the registration form as a pre-chat form by limiting the information requested to the user to only the user's email address or the user name, for example.
* The log-in form is shown only if the registration password field is shown.
* If Settings> Users > Allow Duplicate Emails is enabled and a user enters an already registered email, a new user is created and the email is removed from the old user. The new user will not have access to the old user's messages and conversations.
