I am needing to update the password of one of the users in the DB\security folder in SQL Server 2012. Unfortunately, we do not have a DBA in-house and consequently needing some help. I've been told that I have sysadmin privileges on this SQL Server but I cannot find WHERE to update a user's password in the database. When I googled this, msdn show me how to update a login in the SQL Server 2012 box but this user is NOT listed under the Security\Logins folder on this SQL Server but this user is only under the database\Security\Users folder.
I had tried the ALTER LOGIN username WITH PASSWORD = 'password'; command but I only got this error:
Msg 15151, Level 16, State 1, Line 2 Cannot alter the login 'ATM', because it does not exist or you do not have permission.
I also tried the Use DBName exec sp_password @old = null, @new = '@password1o^|', @loginame = 'userName'
Any help/direction would be appreciated. Thanks.

Did you recently restore this database to a new server? Sounds like you are missing the login, but have the user in the database. You will need to create a login:

CREATE LOGIN ATM WITH PASSWORD = 'enterStrongPasswordHere';

then inside the restored database run this:

exec sp_change_users_login 'update_one', 'ATM'

Yes, the IT manager here recently copied the database from one server to this one. I'll go ahead and try what you've suggested and hope that works on this side.

Thanks so much for your help.

Tried the

Use DBName

exec sp_change_users_login 'update_one', 'ATM' and got this error:

Msg 15600, Level 15, State 1, Procedure sp_change_users_login, Line 98

An invalid parameter or option was specified for procedure 'sys.sp_change_users_login'.

Then I used the following command:

exec sp_change_users_login 'update_one', 'ATM', 'ATM' and I was able to connect via a SQL Server login connection.
