What is banking security?
Banking security encompasses the technical, procedural, and regulatory measures that banks and payment providers use to protect customer accounts and transactions from unauthorised access and fraud. In the UK, the core regulatory standard is Strong Customer Authentication (SCA), mandated by the Payment Services Regulations 2017. Additional layers include encrypted connections (TLS), device binding, biometric authentication, and real-time fraud monitoring.
What are the key security standards for UK banking apps?
UK banking apps must comply with: Strong Customer Authentication (requiring two-factor verification), end-to-end encryption for all data transmission, device binding (linking the app to a specific registered device), and fraud monitoring with real-time alerts. Open banking providers must additionally use tokenised API access rather than storing credentials, and must re-authenticate users every 90 days for AISP connections under FCA rules. The FCA can audit and fine firms that fail to meet these standards.
What is the safest device for online banking?
Apple iOS devices are generally considered more secure than Android for banking due to Apple’s stricter app store controls and OS-level sandboxing, which reduce the risk of malware. On any device, keeping the operating system and banking app updated, using biometric authentication, and avoiding banking on public Wi-Fi or jailbroken/rooted devices are the most important security steps. Using a dedicated device for banking is the highest-security option.
Open Banking in Practice: Open banking adds specific security requirements: all open banking connections must use the UK Open Banking standard, which mandates FAPI (Financial-grade API) security profiles — one of the most rigorous API security standards in use. The FCA’s Financial Services Register is the definitive check for any open banking app. Read our comprehensive guide to banking security and open banking on openfuture.world.

There is no general reason to withdraw savings from FSCS-protected UK banks; deposits up to £85,000 per institution are government-backed and safe from bank failure.
Is it safer to do banking on an app or a desktop browser?
Both are secure if used correctly; the app is slightly more secure as it benefits from device binding and biometric authentication; always ensure your software is up to date.
