Are we able to redirect users who select the temp access to our website?
You can use the advertising features to periodically redirect users to a page, alternatively you could modify the login page to replace the redirect-url to your page rather than the first page the user requested.
This would mean everyone logging in would hit your page straight after login and then could go wherever they want from there, is this what you want?
Yes this is what I want. Can I get some guidance on how to set this “advertising” up. How do I modify my login page to redirect to my page? Thanks for your help.
