Standard sql password. Changing the sa password in MS SQL. Default password sa

You are a respected and trusted database administrator in your organization. You maintain and update several critical services performed by SQL Server in your production environment. You have taken the following steps (reflecting guidelines that any conscientious DBA should follow) to protect your company's SQL Server databases from any type of unauthorized access.

• Removed all built-in SQL Server administrative accounts.
• Removed all users (except for System Administrator or SA) that are members of the SYSADMIN server role (all Windows Accounts and SQL Server accounts).
• We set some extremely complex password for the SA account, which is difficult to guess or remember.
• Perform routine SQL Server maintenance operations under a domain user account that has Database Owner (DBO) permissions on user databases, but does not have SYSADMIN privileges on the system.
• You haven't written down your SA password anywhere to prevent others from finding it out. After all, writing down passwords is not the best approach.

However, because you set such a strong password for the SA and used your domain account rather than the SA account when working with SQL Server databases on a daily basis, the unimaginable happened. You have forgotten your SQL Server SA account password.

You are the only person in your group who knew the SA password. Now you can't remember what it was, and you need to make some confirmations at the server level in the production SQL Server configuration windows. What to do now? Here are some options.

• Try logging in as SA, using whatever passwords you can think of.
• Look for the SA password on your computer's hard drive or in your email (you may have saved it in a file somewhere; this is a bad approach, but it may help).
• Try restoring the Master database from a backup. This will not help in the long run because if you don't remember the SA password, you will experience the same problems.
• Rebuild the Master database. This will not help much as you will lose all system and server level settings and configurations, including accounts, permissions and all server level objects.
• Reinstall SQL Server 2012 and attach all user databases. This may not work as you will experience the same problems as when you reformatted the Master database.

Let's assume that all attempts to log in using the SA account have failed. It's time to call in reinforcements: Microsoft Product Support Team. Here's what its employees have to offer.

There is a backdoor in SQL Server 2012 that allows SYSADMIN access to production SQL Servers. However, your Windows account is required to be a member of the Local Administrators group for the Windows Server systems running SQL Server 2012 services.

SQL Server allows any member of the Local Administrators group to connect to SQL Server with SYSADMIN privileges.

Below are the operations you need to perform to take control of SQL Server 2012 as an SA.

It is completely normal to forget your password from time to time, and this does not mean that even minor inconveniences will arise. The recovery measures I've described will allow you to keep SQL Server running without downtime or password decryption.

Hello everyone, today I’ll tell you how to change or reset password sa sql server. Let me remind you that sa is a user login in MS SQL, which by default has the highest privileges; the account itself is local, often even disabled, but nevertheless often used. A situation may arise that you forgot the password for it and thereby lost access to the databases; today you will learn how to bypass this and restore access to your databases.

sp_password NULL,<вставьте_новый_пароль_тут>, 'sa'

If the message Password validation failed appears. The password does not meet Windows policy requirements because it is too short. Then set a stronger password.

All after this you will reset sa password in sql.

Another option for using osql is like this

then we try to connect under a trusted OS account

osql.exe" -S (local)\your server name -E

And the last frontier
ALTER LOGIN SA WITH PASSWORD= "new_password"
it will replace the password with new_password

Change sa password in exclusive mode

There is a fourth way to change the password for sa, and it is to run MS SQL in single-user mode. What do we need?

The first thing is to stop MS SQL Server, you can do it through services, or you can do it from the command line

net stop MSSQLSERVER

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\MSSQLSERVER

Now you need to set the parameter in the line ImagePath-m will just talk about single-user mode. I got it like this

"C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn\sqlservr.exe" -m -s MSSQLSERVER

Now start MS SQL with the command

net start MSSQLSERVER

SQL is now running in single-user mode and allows any member of the computer's local Administrators group to connect to the instance of SQL Server with sysadmin rights, but you need to tell SQL this. You can view the operating mode in the service properties.

On the command line we write

cd C:\Program Files\Microsoft SQL Server\110\Tools\Binn

sqlcmd.exe: EXEC sp_addsrvrolemember "server name\user name", "sysadmin"

Restart the service and enjoy life, do not forget to remove the -m parameter in the registry later. This is how you can simply reset the sa password in sql, using both built-in and third-party methods.

“sa” is a user login in MS SQL, which by default has the highest privileges; the account itself is local, often even disabled, but nevertheless often used. If you have lost or forgotten the password for this “sa” account, then you will not have access to manage your databases.

Default password sa

Let me remind you that the default password is sa, oddly enough sa

The only requirement is that you must be a local administrator everywhere

Change sa password in sql via GUI

Let's get started, open Start and go to All Programs > Microsoft SQL Server 2012 R2 > SQL Server Management Studio

Or you can open a command prompt and type ssms there.

SQL Server Management Studio will open.

By default, Windows authentication is set, which means that you can only log in with a local Windows account or a domain account, as long as you have rights.

The sa account is disabled by default, but this will not prevent you from changing its password.

ms sql allows you to reset the sa password through its properties, to do this, right-click and select properties from the context menu.

On the general tab you will see a field for entering a new password, the only thing to keep in mind is that if the Require the use of a password policy is checked, you will have to come up with a strong password that meets security requirements, namely

• The password must have a capital letter
• Password must have a lowercase letter
• There must be a special character or number in the password

If you uncheck the box, you can set a new password and save it. The password for the sa user in sql has been changed.

The only thing is that if you want to use the sa account, then you need to enable it; to do this, go to the status item and specify Login Name Enabled.

Another nuance, you remember that you have Windows authentication, which means that this is not suitable for us for sa. Right-click on the server name at the top of the hierarchy and select properties.

On the Security tab, select the SQL Server and Windows Authentication option. Now you can log in using the sa user in sql.

If, when you try to log in, Management Studio gives an error 233 that the connection to the server was successfully established, but then there was an error when logging in, then do the following.

Go to Start > Control Panel > Administrative Tools > Services and restart the SQL Server service.

Then the connection is successful and without errors.
