+# Interim
+
+A friendly, collaborative PostgreSQL front-end for nerds of all stripes.
+
+## Auth
+
+Internally, Interim controls authorization using the `SET ROLE` Postgres command to switch between users. This allows the Interim base user to impersonate roles it has created, without necessarily requiring Postgres superuser privileges itself (unlike if it were to use `SET SESSION AUTHORIZATION`). For each front-end user, Interim creates a Postgres role named (by default) `__interim_{account_uuid}`.
