We know that we can configure a custom domain for an Experiience Cloud site, but can we do that for Lightning Experience? In other words, instead of working from http://mydomainname.my.salesforce.com, can we work from http://mydomainname.com?

You have Options to Serve a Custom Domain in Salesforce. You'll want to read the entire article, plus the other article if you choose to use a Naked Domain (such as mydomainname.com versus www.mydomainname.com). Not all DNS servers support the former, so you'll need to check with your provider. You just need to Add a Domain (Setup > Domains > Add a Domain), and set up the configuration there, then you need to add a CNAME to your DNS entry, which will be in the form of [YourFQDN].[Your18charOrgId].live.siteforce.com, such as www.mydomainname.com.00D000000000123AAA.live.siteforce.com. Other options are available, which I won't get in to here, as the documentation goes into a lot more detail.

  • I think the OP is asking if the full platform (eg https://abc.my.salesforce.com) can use a custom domain, these links are about force.com sites

  • @JeffKranz You can customize almost any feature with Domains, including Salesforce itself, Site.com, and Communities. The documentation states: You can configure domains and their site associations to suit your organization’s unique needs. For example, you can set up a single domain to host your Experience Cloud, Lightning Platform, and Site.com sites. Or perhaps you want a single site on more than one domain.

  • Very interesting to see that it mentions Lightning Platform in that blurb. The rest of the documentation is very specific to site.com / Experience Cloud. We explored custom domains for the platform years ago and hit a dead end, but that's not to say it isn't possible. Just haven't seen or heard of it anywhere.

  • @JeffKranz It's really rare, but I recall seeing at least one instance of a company that did that. It was really impressive, actually. They used branding to make it look like a completely different app. I wish I had a production account for myself just so I could play with it.
