What is a credential based login?
A credential-based login is a type of login that uses the login credentials of an existing account, rather than simply providing the user's username and password. This type of login is most commonly used when accessing secure websites, such as those that require a login to access content or services.
Credential-based logins can be implemented in a number of ways. One common method is to use cookies to remember the user's credentials for subsequent visits. Another method is to require the user to enter their login credentials directly into a form field on the website.
