SQL Server authentication accounts per instance or per database

Do you have accounts (SQL Authentication) per SQL Server instance or per SQL Server database? I was aware the password hashes are stored in sysxlogins table. But I wasnt sure if there was a sysxlogins table per database, or one per instance? If its per instance, how can you tell what permissions each account has over which database? Can you provide perhaps a query to list out the permissions by SQL authentication accounts.

There are some inbuilt SQL Server functions and procedures to view the list of permissions for a login. For detailed study either you can go to MSDN or the below link.

Thanks. But as per the question, is there a set of accounts per database, or per instance. Is there a sysxlogins per database or per instance?

Raja Jegan R

Ideally syslogins table will be available in the master database per instance and will be shared across all user databases and sysusers table will be present in all user databases with individual entries inside it.

Do all the later versions of SQL Server still support the mixed mode authentication?
