How to fix 'dbo' user should not be used for normal service operation vulnerability in SQL Azure Database.

• Need to create a new login and new user with the lowest possible priveledges.
• New login can be created in the 'master' database only. As of now, there is no way to change the database to 'master' from Azure portal.
• Use 'SQL Server Management Studio' using the admin user created at the time of creating a database.
• user master; 
• CREATE LOGIN appusr WITH password='xxxxxxx';
• use yourdb; 
• CREATE USER appusr FOR LOGIN appusr; 
• EXEC sp_addrolemember N'db_datareader', N'appusr'; 
• EXEC sp_addrolemember N'db_datawriter', N'appusr'; 
• GRANT EXECUTE TO [appusr];
