Support access is granted, time-boxed and logged
Our own people cannot open a customer's hotel. The account lets them in for a window, the session is logged, and the account can see afterwards who was inside and when.
Every SaaS product has a support login that can see everything, and every customer has to take it on trust. Here the trust is a mechanism.
The grant
An account administrator grants access — to a named platform user, for a number of hours, with a reason. Until then the platform user sees the account's name and its subscription, and nothing inside it.
The session
Entering an account is a session with a start, an end and a log entry. Everything the platform user does inside is written against their own name, not the account's. Leaving is explicit; the window closing is automatic.
Afterwards
The account sees the sessions: who, when, for how long, why. A tenant cannot become a platform user by any route; the two are different kinds of login, and the suite proves it.
