Broker Authentication Integration

@bizmanas

Hello, You need a secure JavaScript + PHP integration that authenticates users with Zerodha and Fyers, captures their credentials, and stores them safely in a database with custom security beyond standard encryption. With 18+ years of experience (4.9⭐ rating, repeat clients), I’ve delivered broker API integrations, secure credential storage, and PHP/JS-based authentication flows across financial systems. I also bring strong expertise in SQL schema design, encryption techniques (AES-256, hashing + salting), and tokenized storage to ensure sensitive broker data is well-protected. My Approach UI Development Two secure buttons: Login with Zerodha / Login with Fyers. Clear, minimal UI for seamless user flow. Authentication Flow Call broker APIs (Zerodha Kite Connect, Fyers API v2). Retrieve tokens and securely pass back to backend. Validate responses before storing. Database & Security SQL schema with normalized tables for Zerodha & Fyers credentials. Sensitive fields (TOTP, PIN, secret keys) stored with AES-256 encryption + unique per-record salt. Access tokens hashed and rotated securely. Enforce HTTPS, secure headers, CSRF protection, and prepared statements. Deliverables Complete working PHP + JavaScript code. SQL schema (create tables, constraints, indexes). Security implementation documentation (how credentials are encrypted & retrieved safely).

Hi, I can develop a secure JavaScript + PHP solution to authenticate users with Zerodha and Fyers, including broker-specific login flows and safe storage of credentials in a database. I’ll build a clean UI with broker buttons, implement the complete authentication process, and design an SQL schema to handle required fields (username, client ID, TOTP, tokens, etc.). For security, I’ll go beyond basic encryption by adding salted hashing, tokenization, and strong encryption measures to protect sensitive credentials. Regards, Mutahra
