You can do it.
1. Create a table called login has @list to field UserId and Password.
2. Create a unbound form for login having two text box (UserID and Password) and two button (Log in and Cancel).
3. Create a select query on login table that takes two parameters for loginid and password from the login form.
4. Create a form from the query created.
5. Make the queried form a sub form of the login form that not visible.
6. Now Add a Macro to the login captioned button in login form.
The marcro steps are given bellow.
a. MsgBox in action if user id not given.
b. StopMacro in action if user id not given.
c. MsgBox in action if password not given.
d. StopMacro in action if password not given.
e. Requery in action
f. MsgBox in action if user id and password in login form and user id and password in sub form not matched.

Just be aware that because Access is both the client and server, any security you attempt to apply to an access database can be undone by any user with access to it.Comment
