What is Login
Introduction to Login
In computer terms, "login" refers to the process of gaining access to a system, application, or website by entering authorized credentials such as a username and password. It helps authenticate users and ensures that only authorized individuals can access restricted areas or services.
How Does Login Work?
When a user logs in, they provide a unique identifier (such as a username) and a secret key (such as a password) to prove their identity. The system then checks these credentials against a stored database. If the details match, the user is granted access.
Importance of Login Security
The login process plays a vital role in protecting user accounts and sensitive data. To enhance security, additional methods like two-factor authentication (2FA) are often employed, requiring users to provide an extra form of verification beyond the password.
Types of Login Methods
Different systems may use various login methods, such as traditional username-password logins, biometric logins (e.g., fingerprint or facial recognition), or single sign-on (SSO), where users can log in to multiple systems using a single set of credentials.
