There may be times when it’s useful to view either the internal Rock site or the external organization site as an individual other than yourself. For example, if someone calls needing technical support because of a problem with their person profile, an admin may want to view the page while logged in as that person. This allows the admin to see exactly what the person sees. Rather than creating a new login—which can result in duplicates in the database—Rock uses person tokens, which allow Rock admins to log in as (i.e., impersonate) users without requiring passwords. This not only makes troubleshooting easier, but it also helps keep your database tidy. Anytime an admin impersonates another user, a record of the login is kept in the user's history tab. Tokens are configurable, so you have control over how long they’re valid for and how many times they may be used before expiring. Let’s take a look at how to do this.
