I am attempting to make my companies Sharepoint site a little more user friendly and easier to navigate. Our users complain about the Frequent Sites page regularly and i would like to reroute users upon sign in, to our Home page. I'm hoping someone here can help me. Thanks in advance.
By "frequent sites page", I assume you mean the sharepoint page, located at "_layouts/15/sharepoint.aspx"? If so, how are your users getting there to begin with? The system doesn't take users to that site automatically. Perhaps their browser has it set as the home page? If so, the simple solution is to set whatever page you want as the home page in their browser settings.
Though, another part of that answer might be training for the users as to the purpose and functionality of the the listing of frequent sites. It's difficult to imagine a knowledgeable user complaining about it, as this is a common element that shows up in windows and other sites. On the start menu, we have "most used", and other apps will also surface content or organize content based on usage.
I know what you mean. After users click "SharePoint" app, they will go to the _layouts/15/sharepoint.aspx page. And you want to make this default page as your homepage.
This is by design and can cannot be routed to another page.
The only workaround I can imagine is that let your users save your homepage(SitePages/Home.aspx) as a bookmark. Then they can directly click the bookmark to signing into your homepage without signing into Office.com.
