Microsoft Access 7.0 and 97 MDB files can be password protected. This article demonstrates how to change the password associated with a Microsoft Access 7.0 or 97 MDB file.

The database password can be changed by using the NewPassword method. The following example changes the password of the MyDB.mdb database from "MyPassword1" to "MyPassword2":
