Enable full‑disk encryption, secure boot, and biometric unlock with strong fallback codes. Remove unused apps that carry vulnerable SDKs. Disable notifications on the lock screen to hide sensitive codes. Regularly review app update notes, focusing on security fixes that quietly close dangerous holes exploited in the wild.
Use a dedicated profile or container for trading sessions, blocking third‑party cookies and unnecessary extensions. Enable HTTPS‑only mode and strict tracking protection. Clear site data frequently. These boundaries reduce cross‑site leaks, malicious injection, and session fixation that can silently bind your broker login to an attacker’s origin.
Prefer cellular or trusted home networks, and turn off auto‑join for unknown hotspots. If public Wi‑Fi is unavoidable, use a reputable VPN and disable file sharing. Watch captive portals closely; fake gateways harvest credentials. DNS over HTTPS and certificate pinning inside apps further tighten defenses against interception.
