In web application development, ensuring the security of user passwords is crucial. Here are some best practices to handle and store user passwords securely:

1. Hashing: Hash passwords using strong one-way hashing algorithms like bcrypt or Argon2. This makes it computationally expensive for attackers to retrieve the original password.
2. Salt: Use random salts for each password before hashing. Salting prevents attackers from using precomputed tables (rainbow tables) to crack passwords.
3. Encryption: Encrypt sensitive data, including passwords, during transmission using secure protocols like HTTPS and at rest using encryption algorithms like AES.
4. Password Complexity: Enforce strong password policies that require a minimum length, a combination of lowercase and uppercase letters, numbers, and special characters.
5. Two-Factor Authentication: Implement 2FA to add an extra layer of security, requiring users to provide a second form of verification.
6. Regular Updates: Keep software and libraries updated to fix any security vulnerabilities.

By following these best practices, you can significantly enhance the security of user passwords in web applications.
