User Login Functionality
The login functionality is a crucial part of any online platform, allowing users to access their accounts securely. In this section, we will explore the different aspects of user login functionality and its importance.
- Authentication: This is the process of verifying the identity of a user by comparing it with the stored credentials in the database.
- Authorization: After authentication, the system checks if the user has the required permissions to perform certain actions on the platform.
- Billing and Payment: If your platform offers billing services or payment gateways, this is where you would handle these transactions securely.
Common Security Measures
The following are some common security measures used to protect user login functionality:
- Hashing and Salting: This involves storing passwords in a hashed format, making it difficult for hackers to retrieve the original password.
- Password Strength Checking: Many platforms use tools like bcrypt or PBKDF2 to check the strength of user-provided passwords.
- Two-Factor Authentication (2FA): This adds an extra layer of security by requiring users to provide a second form of verification, such as a code sent to their phone or email.
