Hi Kiran Kumar,
Windows Authentication in SQL Server, also known as integrated security, relies on the user's existing Windows credentials to authenticate with the SQL Server instance.
This means the user doesn't need to provide separate SQL Server login credentials; SQL Server leverages the Windows authentication token to grant access.
Hope this will help you!

Windows Authentication is a security mode in SQL Server where the database engine relies on the Windows operating system or Active Directory to verify the user’s identity instead of using SQL-stored passwords.
Key points (single-line pointers):
Windows Authentication uses the Windows OS or Active Directory to validate user identity.
No SQL Server–specific passwords are stored; authentication relies on Windows security tokens.
Users authenticate to Windows first, and SQL Server accepts their Windows access token for login.
Permissions are controlled through Windows accounts and AD groups mapped to SQL logins.
Group-based access lets admins manage SQL permissions centrally via Active Directory.
Kerberos enables secure token delegation across multi-tier applications.
Security policies like password complexity and lockout are enforced by Windows, not SQL Server.
Credential exposure risk is reduced because no SQL credentials are transmitted.
Best suited for domain-joined corporate environments with centralized user management.

Windows Authentication Mode in SQL Server is a security mechanism that allows users to connect to SQL Server using their Windows user accounts (Active Directory credentials).
In this mode, SQL Server relies on Windows to authenticate users. The SQL Server does not store user names or passwords; instead, it trusts the Windows operating system to verify login credentials.

Windows Authentication Mode in SQL Server means that users can connect to the database using their Windows (domain or local) account without needing a separate SQL Server username and password.
