we need on single account which we may share with a group of people. we don’t want that tey are able to change anything (password, name). They sould only view some protected information. We can’t use possword protection, because this is to insecure (keeps saved in browser for 10 days).

Here is what I found:

add_action( 'load-profile.php', 'd_disable_editing_my_profile' ); – to prevent changing profile
add_filter('login_redirect', 'admin_default_page'); – to redirect users

What did not work for us: prevent password-reset link only for this users + redirect other users to dashboard instead main page.

Is there a plugin or something else that could solve this?
