Describe the approach you used to implement user verification in your last project.

In my last project for user verification, I used the following approach:

• Authentication: implemented login and password verification using a database where passwords were stored as salted hashes (for example, using BCrypt).

• Authorization: after successful authentication, a JWT token was issued to the user with specific access rights.

• Data validation: before user verification, data was validated on the server side to prevent SQL injections and other vulnerabilities.

• Security: used HTTPS to protect data transmission and limited login attempts to prevent brute-force attacks.

Example of password verification code in Java using BCrypt:

import org.mindrot.jbcrypt.BCrypt;

public boolean checkPassword(String candidate, String hashed) {
    return BCrypt.checkpw(candidate, hashed);
}
