SharePoint 2016 Central Admin - Security - Manage Trust

When you click Manage Trust link, you will land on the Trusts page. This page will give an option to the SharePoint administrator to manage the trust relationships for this Farm.

Manage Trust page’s direct link: /_admin/ManageTrust.aspx

SharePoint has an ability to connect to other SharePoint Farms to consume the Service Applications or connect to Office Online Server or connect to the Workflow Manager Farm (dedicated Farm). For SharePoint to communicate to other Farms, we have to build a trust between the Farms. We need to exchange the certificates between the Farms to build a trust between the Farm.

We can build the trust (exchange the certificates) via Powershell as well as via Central Admin. SharePoint 2016 Central Admin gives us an option, where we can build the trust between the Farms by adding the certificate.

There are couple of situations, where have to build a trust.

1. If you want to consume a shared Service from a publishing Farm, then we have to build the trust between publishing and consumer Farm.
2. If we have a dedicated Workflow Manager Farm and use https for communication then we have to build Trust with Workflow Manager Farm.
3. Similarly, if we have a OOS Farm then we have to build the trust relationship with that farm.

In Central Admin Manage Trust options, we can add a Root or STS certificate, edit a certificate or even delete a certificate.
