December 2024: Implemented OTP and PIN-based authentication across nocode-saas and nocode-ui, delivering passwordless login paths, policy-driven security, and improved developer ergonomics. Backend security model expanded with new security-database tables, SMS OTP service (with a mock fallback), and policy checks before setting credentials. UI/UX improvements enable MFA-based login, passwordless login, and removal of unused UI parameters. Robust cryptography and signing capabilities introduced, including HMAC signer and common signature algorithms, plus a reactive signer pipeline. Policy management APIs and policy fetch endpoints were added to support password-type based checks and policy-driven onboarding. Code quality and maintainability improved via dead code removal, import optimizations, internal utilities enhancements, and clearer policy/config flow. Key reliability improvements implemented for KIRun/KIRunFunction and output event handling to avoid empty or mis-specified results.
