How can we communicate the ability to use the same login credentials across multiple sites?

1. How do I pass login credentials through URL?
2. Can you share login credentials?
3. What allows a user to login in once to gain access to different resources which reduces the number of logins and passwords a user has to remember?

How do I pass login credentials through URL?

It is indeed not possible to pass the username and password via query parameters in standard HTTP auth. Instead, you use a special URL format, like this: http://username:[email protected]/ -- this sends the credentials in the standard HTTP "Authorization" header.

Can you share login credentials?

Credential sharing is the practice of using someone else's digital identity to gain access to a platform. One example of credential sharing is providing another person with one's credentials in exchange for payment, and then signing in using their credentials.

What allows a user to login in once to gain access to different resources which reduces the number of logins and passwords a user has to remember?

Single sign-on (SSO) is a session and user authentication service that permits a user to use one set of login credentials -- for example, a username and password -- to access multiple applications.
