Mobile Banking Security Basics

Protect your accounts on mobile

The guide covers device hardening, strong authentication, safe networks, transaction alerts, and what to do if a device is lost or compromised.

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.
