I once forgot my SQL Server sa password and I reinstalled MS SQL at last as I failed to find some good methods to solve the problem. What annoying and terrible experience it is! In order to avoid reinstalling SQL Server for a second time due to the same reason, so I collect some methods to reset SQL Server Password for sa account.

  • 2. In Object Explorer, open Security folder, open Logins folder. Right Click on sa account and go to Properties.
  • 3. Type a new SQL sa password, and confirm it. Click OK to finish.

After restarting SQL Server and all its services, you can log into SQL Server by sa login with new SQL sa password.
