A logon (or login) is a procedure that enables an entity, usually an end user, to access a secure system such as an operating system, application, service, or website by authenticating credentials like user ID and password.
Logon can also be done using biometrics or smart cards as alternative methods.
The logon process is essential for verifying user identity before granting access to resources, and can differ depending on the system and context, such as local logon, network logon, or remote logon in Windows environments
