With such a statement, you can recreate a login on a different SQL Server instance while preserving the password.
#Hash password generator password
While there is no way to decrypt a password of a SQL login, you can script out the password hash and use it to compile a CREATE LOGIN statement that contains the password in hashed form. However, a password that was hashed in 2012 or 2014 cannot be used on a pre-2012 instance. That means that a password that was hashed on a pre-2012 instance can be used in a CREATE USER statement on a 2012 or later instance. Effortless security Anywhere you create a new account, LastPass is there, too.
With LastPass Premium and Families, anything you create and save on one device is instantly available on all others.

The password hashes are backwards compatible, but they are not forward compatible. LastPass is free to use as a secure password generator on any computer, phone, or tablet. You can read a little bit about the history of password hashes before SQL Server 2005 in Laurentiu Cristofor's blog SQL Server 2005, 20 R2 use SHA-1 while SQL Server 2012 introduces SHA-512 as password hashing algorithm. SQL Server has changed the password algorithm several times throughout the different versions. If you now execute this statement on another server, you will be able to login using that SQL Login and the same password. All we really need is the hashed password value, and a way to tell SQL Server to create the new login with that password hash.ĬREATE LOGIN ASQLLogin WITH PASSWORD = 0x0200C6FAAFFE9C6BAA377C6E74DF8FC9819860E54B31EAE9F4D326D10B8707C36F030DE5826577B676E2F8CB02FDB31BD829691FD55E1C616F87122D926B9C27FB13356A63D6 HASHED Therefore, to copy a login to a new SQL Server instance we do not need to know the original password. That hash value is all that SQL Server needs to be able to check the password during authentication. In sys.sql_logins - Getting to know your SQL Logins and LOGINPROPERTY – Getting to know your SQL Logins even more I showed you two ways to retrieve the hashed password for a SQL Login. SQL Server does follow best practices and therefore only stores a salted hash of the password. However, what you can do is pretty close. You can script the password? What happened to all the security best practices of never storing a password in a decryptable manner? However, there is a way to script the login together with its password. In many situations that is not convenient and depending on your security setup, you might not even have access to the password. But, to be able to do that, you need to know the password.
To keep the password the same, you need to manually replace the random password with the existing one. Generating a random salt uses the pseudo-random number generator in your browser so chances are its not using cryptographically secure randomness. _é>E', DEFAULT_DATABASE=, DEFAULT_LANGUAGE=, CHECK_EXPIRATION=OFF, CHECK_POLICY=ON.* For security reasons the login is created disabled and with a random password.
