What Is Link Account?

When a user who has Kintone license is invited as a guest to a guest space of other Kintone, both Kintone accounts are linked by the "Link Account" feature.

By linking accounts, it becomes possible to open other Kintone to which the user is invited, without logging in again to the top page of the licensed Kintone.

Also note that the guest user can use the service for free when the Link Account is activated.
