Databases don't have logins and passwords, servers do. You need to add a SQL login to the SQL instance. If you're sysadmin or security admin you can do it yourself, otherwise ask your DBA.
Management studio, open object explorer and connect to the server. Expand out security, right-click logins -> new login
