How to Change SQL Server System Administrator (SA) Passwords: A Step-by-Step Guide

What types of authentication are supported by SQL Server? Introducing the need to change SQL server system administrator (SA) passwords for improved security of sensitive databases, SCOPE attempts to provide a user-friendly guide for making the necessary changes. Through this guide, users will be able to quickly and easily update their passwords and ensure they are not vulnerable to unauthorized access or data loss. This article provides a step-by-step guide on how to make the necessary changes, along with recommendations on the best approach for change the SA password in SQL Server.

What is a System Administrator?

System Administrator, or SA, is an account in Microsoft SQL Server, which is used to manage the entire server. This includes granting permissions to users, creating databases, creating tables, deleting and modifying data, and granting server roles. As you can imagine, the SA account has unrestricted access to all data in the server and is therefore very vulnerable to cyberattacks.

For this reason, it is highly recommended that SA passwords be changed on a regular basis to prevent unauthorized access. It is important to note, however, that the SA password is limited to eight characters, and thus must be a combination of both numbers and letters, as well as symbols.

How to Change SA Password in SQL Server?

Step 1: Connect to the SQL Server Instance

The first step in changing your SA password in SQL Server is to connect to the instance. To do this, you will need to open Microsoft SQL Server Management Studio in the programming language of your choice, such as SQL Server Transact-SQL or PowerShell. Then, enter your SA username and password to connect.

Step 2: Execute the ALTER LOGIN Query

Once you have successfully connected to the server instance, you can execute the ALTER LOGIN query. This query is used to change the authentication mechanism, as well as update the SA password. For instance you can type in “ALTER LOGIN sa WITH PASSWORD=‘YourNewPassword’”

Step 3: Restart the SQL Server Services

Once you have successfully executed the query, you should restart the SQL Server services. This is important because the changes that you’ve made to the SA password will only take effect after the services have been restarted. To Restart the services, type in “net stop” followed by “net start”.

Best Practices for System Administrator Password

When changing the SA password, it is important to consider the following best practices to ensure that it is secure:

  • Choose a Strong Password: The password should be at least 8 characters long and a combination of numbers, symbols, and both upper and lowercase letters.
  • Change Passwords Regularly: It is recommended that passwords are changed at least every 60 days.
  • Do Not Reuse Passwords: Even if the same password is being used for a different account, it should be changed periodically.
  • Use a Password Manager: Password managers store passwords in an encrypted file, meaning they cannot be guessed by hackers.
