Login

In computer security, logging in (or logging on, signing in, or signing on) is the process by which an individual gains access to a computer system or program by identifying and authenticating themselves.

"Logon" redirects here. Not to be confused with Logone River.

The user credentials are typically some form of username and a password,[1] and these credentials themselves are sometimes referred to as a login.[2]


In practice, modern secure systems often require a second factor such as email or SMS confirmation for extra security.


Social login allows a user to use an existing cell phone number, or user credentials from another email or social networking service to sign in or create an account on a new website.


When access is no longer needed, the user can log out, log off, sign out or sign off.
