Let users choose their organization at sign-in
This guide explains how to let users choose or enter their organization on the sign-in page. For example, /login is the sign-in page of the built-in organization. With this option on app-built-in, users choose an organization first and Casdoor sends them to /login/<organization>.

The organization choice appears only on /login and /login/<organization>, and only if the application is the default application of the organization or app-built-in.
Return to the same organization
When a user visits the sign-in page of an organization, such as /login/my-org, the browser remembers the organization. When the session of the user expires, Casdoor sends the user to the sign-in page of that organization instead of /login.
If the browser hasn't stored an organization, Casdoor sends the user to /login, where the user chooses the organization if the mode is Input or Select.
