Harden the device
Enable OS updates, screen lock, full-disk encryption, and disable sideloading on primary devices.
Secure the banking app
Use app-based 2FA or hardware keys where supported, and avoid SMS-only codes when possible.
Use trusted networks
Prefer cellular or trusted Wi-Fi; avoid transactions on open Wi-Fi unless using a VPN.
Alerts and recovery
Turn on transaction alerts, store bank contact numbers, and be ready to freeze cards if the phone is lost.
