Login page caching and autocomplete
The Login page caching and autocomplete feature, which stores users' login details (just the list of usernames but not the password), is as per the upcoming section.
Enable caching and autocomplete on login page
The Enable caching and autocomplete on login page option enables users' browsers to store username text and so, after their initial log in, usernames are automatically set in the User Name field on the login page.
Note
This option is enabled by default.
