I'm currently developing a website that requires robust user authentication to ensure data security and user privacy. However, I'm facing challenges in implementing a secure authentication system. I've used basic authentication methods, but I'm worried about potential vulnerabilities and security loopholes.

Here are the main issues I'm encountering:

1. Vulnerabilities in current authentication process: I've implemented a basic username/password authentication system, but I'm concerned about potential vulnerabilities like SQL injection, brute force attacks, or session hijacking.
2. Lack of multifactor authentication (MFA): I want to enhance security by implementing MFA, but I'm unsure about the best methods and tools to integrate for this purpose.
3. Secure password storage: I need guidance on the most secure way to store user passwords. I've been using hashing algorithms, but I'm not sure if this is enough to prevent password breaches.

What I've tried so far:

• Implemented basic authentication using hashing algorithms for passwords.
• Explored some third-party authentication services but unsure about their reliability and security.
• Researched MFA methods but need practical advice on integrating them into my website.

Request for assistance: I'm seeking advice, best practices, and practical solutions to improve the security of the user authentication system on my capcut mod apk website. I'm open to suggestions, recommended tools/libraries, and any resources that can help me build a robust authentication system while ensuring user data safety and privacy.

Any guidance, tips, or recommended readings would be highly appreciated. Thank you!
