When was the last time the SQL Server sa password changed?

Solution

The first step in the process is to find out when the sa password was last changed. If this timeframe is unacceptable to your organization, then steps need to be taken to understand where the sa login is used and how the application can be modified to use another login.

SQL Server 2000 – sa password changes

In SQL Server 2000 a documented process does not exist to determine when the sa password was changed. The best means to determine if the sa password has changed is based on the value from the updatedate column in the master.dbo.syslogins table. This value seems to be the only possible column to determine if any property (default database, default language, etc.) for the sa login has changed. Since the sa properties do not change frequently, the value for this column should be a reasonable, but not an absolute indicator of when the sa password was last changed. Reference the code below to determine the value for the sa login's updatedate column.

SQL Server 2005 – sa password changes

Unfortunately, SQL Server 2005 suffers from the same self documenting issue as SQL Server 2000 as it pertains to the last time the sa password has changed. The modify_date of the sys.sql_logins catalog view can be used as an indicator of when the last property (default database, default language, etc.) for the login has changed. Just as is the case with SQL Server 2000, this value does not guarantee the datetime stamp of the password change, but rather any property change. Since the properties do not change frequently under normal circumstances this value can serve as a reasonable, but not an absolute indicator of when the sa password was last changed. If other properties have changed, the modify_date is not a true indicator and other research/documentation is needed to determine the last sa password change date.
