How to add a resident, appoint board officers and give a supplier's workers access to the app.
A user's profile is not picked from a standalone permission screen: it follows from what that person is in the community. A registered owner is a resident; if they also hold a board office, they get board permissions; and someone working for a supplier signs in as a worker. Each case is handled in a different place.
The property manager and the members of the board. Neither residents nor workers can change their own profile or anyone else's.
From the Community tab, in the users block. Registering an owner or tenant and linking them to their property gives that person access with the resident profile.

Double-check the email: access, meeting notices and urgent alerts all go there.
Board permissions come with the office. In the same Community tab, the Board block lists the current officers and their history. Give a resident an office and they start managing the community with the board permissions described in the President and board guide.
It works the same way in reverse: when the term ends, the person becomes a resident again and the management actions disappear. The history keeps who held each office and when — what you need when the board is renewed after the annual meeting.
Workers are not added as residents: they hang off a supplier. In the Suppliers tab each supplier has its people, and those people sign in with the worker profile.

Their access is limited to the community — or communities — the supplier serves.
