Best Solution to Unlock SQL Server?

If you are looking for the best method to unlock an SQL server, then you can try the SysInfo MS SQL Server Password Recovery Tool. It can crack all types of SQL passwords, such as encrypted and unencrypted passwords. This tool sets the new password for user accounts in SQL Server by replacing the original password. It also successfully recovers the different passwords of MDF files. In addition, it also reset both the User’s and Administrator's passwords from the SQL MDF file, and an Auto-detect feature. It is compatible with all the versions of Windows OS.

 ​To unlock a SQL Server account without coding, you can use SQL Server Management Studio (SSMS):​

Connect to the Server: Open SSMS and connect using an account with sufficient privileges.​

Navigate to Security: In the Object Explorer, expand the server instance, then expand the "Security" folder, and click on "Logins".​
Axial SQL

Modify the Locked Login:

Locate and right-click the locked login, then select "Properties".​

In the "Login Properties" window, go to the "Status" page.​

Under "Login", select "Enabled".​

Under "Login must change password at next login", ensure it's unchecked if you don't want to enforce a password change.​

Click "OK" to apply the changes.

 Unlocking SQL Server typically refers to restoring access when a user login is locked, disabled, or the server is rejecting authentication attempts. The best and most practical solution—especially for beginners or those from non-database backgrounds like students of an Internet of Things course—is to use SQL Server Management Studio (SSMS) with Windows Authentication and an administrator account.

Step-by-Step Guide:
Use Windows Authentication: If SQL Server is set to allow Windows Authentication, you can log in with your Windows user account—preferably one with administrative privileges. This method bypasses locked SQL logins and allows direct access.

Login Through SSMS: Open SSMS and select "Windows Authentication" in the login window. This is the easiest and safest way to access SQL Server if SQL logins are causing issues.

Use Single-User Mode if Locked Out: If no accounts are working, restart SQL Server in single-user mode. This special mode allows only one connection and is often used for emergency maintenance.

Unlock or Enable the SQL Login: Once logged in, navigate through the graphical interface of SSMS:

Expand the “Security” folder.

Click “Logins.”

Right-click the locked or disabled login → choose “Properties.”

From there, you can enable the login and set a new password.

Review Server Authentication Mode: Ensure that SQL Server is set to allow both SQL and Windows Authentication. This setting can be changed via the server properties in SSMS.

Final Tip:

For students or professionals in an Internet of Things course, understanding how to manage databases like SQL Server is essential. This approach avoids complex coding and helps maintain secure and smooth operation of connected systems and devices.
