Biometric authentication methods such as Face ID, fingerprint, and iris scans are now common in digital banking, mobile apps, and high-security systems. This paper analyzes best practices in designing user-friendly biometric authentication, focusing on UX patterns, accessibility, privacy, and security. Based on current research, industry guidelines, and application in finance, the goal is to help designers build secure and trustworthy interfaces that are easy for all users while complying with regulations. Design principles, usability outcomes, technical barriers, and future trends are discussed, with IEEE-style references and clear formatting for direct practical use
