Administrator: username admin · password admin@123 — sees all zones, all cases, manages officer logins.

Investigating Officers (PI): default password cyber@123. Username = your name without "PI", no spaces, then a dot and zone code.
e.g. PI P D MAKWANA (Gandhinagar) → pdmakwana.gnr · PI R R SOLANKI (Saurashtra) → rrsolanki.sau
Zone codes: GNR · VAD · SAU · SUR · BOR. The admin can view the full username list under Officers.

Note: this is device-local prototype auth. For real multi-user deployment, move authentication to the server (FastAPI) backend.
