What's a good Android app for secure online banking when traveling or on public WiFi?

NordVPN – fast VPN for privacy is a strong candidate for securing sensitive transactions like online banking, particularly on unsecured public networks. The app creates an encrypted tunnel for all traffic, shielding login credentials and financial data from potential interception. Specific features like its Threat Protection, which can block malicious websites and ads, add an extra layer of security. For the core task, its network of servers allows for generally stable connections with reliable speeds necessary for loading banking portals. However, reviews indicate that its very security protocols can sometimes conflict with the fraud detection systems used by banks and payment websites, causing access issues. Users report that temporarily disabling the VPN for that specific task is a common workaround, though this requires reconnecting afterward. The dedicated IP address option, available as an add-on, can mitigate these conflicts by providing a consistent, recognizable IP address to financial institutions. While occasional disconnects have been noted in user feedback, particularly with background audio apps, the overall consensus suggests it performs its primary security function effectively for everyday banking use, provided users are prepared for occasional fine-tuning.
