Transfer logins and passwords between instances of SQL Server: sp_help_revlogin script
Transfer logins and passwords to destination server (Server B) using scripts generated on source server (Server A)
Step 1:
Create stored procedures that will help generate necessary scripts to transfer logins and their passwords. To do so, connect to Server A using SQL Server Management Studio (SSMS) or any other client tool and run the following script:
EXEC sp_help_revlogin
The output script that the

Step 3: Run the following statement in the same or a new query window:
EXEC sp_help_revlogin
The output script that the
sp_help_revlogin stored procedure generates is the login script. This login script creates the logins that have the original Security Identifier (SID) and the original password.Steps on the destination server (Server B)
Connect to Server B using any client tool (like SSMS) and then run the script generated in Step 4 (output of sp_helprevlogin) from Server A.
