Only simple way I can think of is to try and see if you can adjust a UI message record.

Is it possible to edit the login block (shown in the inset picture above)? I’m using global client script to manipulate the DOM in order to change “Login” to “Legacy Login”, but the screen has to render before I can execute the script so it looks a little sloppy when the page first loads, and the script interrupts your typing when you’re trying to log in.

This is possible with the Content Management System in ServiceNow. You would have to set up separate login pages in your CMS for each company and then use the page suffix as the pointer to the different login pages. You shouldn’t even have to set up a full CMS site to do this. Your URLs would look something like this…

https://demo.service-now.com/cms/company1_login.d…

Something that won’t be so easy to separate is the page that users end up on when they log out of the system. Typically users are brought back to the standard login page and I don’t know of a simple way to get them back to the same company-specific page they hit when they came in. You’d probably just have to make your standard login page look as generic as possible. I’m not sure what challenges you might face with this but it looks like it would work.

For example,

servicedesk.company1.ca >> custom login page 1

servicedesk.company2.ca >> custom login page 2

servicedesk.company3.ca >> custom login page 3
