sql-server-2008

I have the following table...

TABLE: Accounts
  ID (int, PK, Identity)
  AccountType (int, PK)
  Username (varchar)
  Password (varchar)

I have created a composite key out of ID and AccountType columns so that people can have the same username/password but different AccountTypes.

Does this mean that for each foreign table that I try and link to I'll have to create two columns?

I’m using SQL Server 2008
