relating tables

[ysfpsu]

I have a table with the following fields: Login ID, Description Password, Login Type, Location, Status. For every Login ID there are some old passwords that had different effective dates. I want my form or table to behave so that I can enter all the old passwords with the effective dates and keep adding to this record. I know it has something to do with subforms but I don't know how to do it. Please help.
Thank you
Yusuf

What are you relating this table to? Are you saying that you are maintining a history of passwords per login?
