MS Access uses the underlying Jet Database Engine. Using Access Password, you can recover passwords for any Jet databases, not only Access databases. Note that the security model in MS Access is quite complex (although it is insecure).
There are two different password types: user passwords and database passwords. Read this article for more information on Access password types. Note that database passwords were introduced in Access 95. MS Access v2.0 does not support database passwords. In MS Access 2007, the security model has been redesigned; database security has been improved, and user passwords have been removed at all.You can find more information on password types in MS Access in this article.
User passwords are stored in a so-called system database (.mda (old Access 2.0) or .mdw (Modern versions) file).
IMPORTANT NOTE: the system database is required to crack a user password. If the system database is lost, there is no way to recover user passwords (we are developing a solution for this situation, it will be available in the next release. If your system database is lost, please contact us for further information). To recover a database password, select the database itself (.mdb or .mde file). To recover user passwords, select the system database (.mda or .mdw file).
Access Password can automatically find the currently registered system database. Note that it is very important to use the correct system database. Often password problems with Access databases are caused by using an improper system database.
