The Ad Sales Genius Portal requires you to use a specific address, link, or url. The company you're advertising with can provide you this address if you haven't already received it from them. The link should include "?id=" followed by many letters, numbers, and symbols.
It's this address that you will want to bookmark or save. If you've already bookmarked the "https://portal.adsalesgenius.com/login" link, you can just modify it and replace the address with the longer version that includes the "?id=".
