When field app access depends on someone sending a separate invite, new starters often wait days to get in and people who leave keep access longer than they should. Tying access to the company’s single sign on setup removes that manual step.
Ideally, users are created and removed automatically based on groups in the company’s identity system, so adding someone to the right group gives them access with the right role. That keeps access in line with employment status and saves administrators from managing users in two places.
