Out of the box, all members of your company domain are authorized to your Vect repository.
Additional collaborators, outside of your company domain, can be invited as guests.
Guests have the same permissions as users of your company domain, and can view and edit your parameters on Vect.
Add a new guest by creating a new Change, append the guest’s email address to the list of guests found in .vect/authorizations/guests and deploy the Change.

The link is of the following form:
<https://app.vect.io/repository/><your-org>/<your-repository>
