Enterprise applications face constant threats from credential stuffing and brute-force attacks. This article explores a comprehensive login security architecture combining graphical and slider CAPTCHAs, SMS verification codes, and Redis-based rate limiting. The approach uses Spring Boot on the backend, Vue for web frontend, and Uniapp for mobile clients. Key considerations include balancing user experience with security, managing Redis key expiration for rate limits, and handling SMS delivery failures gracefully. The pattern is widely applicable across industries and tech stacks, making it a valuable reference for developers building secure authentication systems.
