How to decrypt an MS Access database file to open it

MS Access database is a part of the Microsoft Office suite for creating database files. Users usually use it to store data in rows and columns format. As is known to all, Microsoft Access provides a facility to you for setting a password on the database. So, any unauthorized people or corporate spies become unable to access or modify the Access ACCDB or MDB file. Undoubtedly, keeping data safe with encryption is a necessity.

Method 3. Recover the open password for the .accdb file using MS Access Password Recovery

Do you have concerns about privacy security when using online services? If so, try a piece of desktop Access database password recovery software.

As the title implies, MS Access Password Recovery is capable of recovering the forgotten Access password. You can use the software to retrieve the open password for the ACCDB file created with MS Access 2007, 2010, 2013, 2016, 2019. The app comes packed with three attack modes to crack the password. They are “Dictionary Attack”, “Mask Attack”, and “Brute Attack”. Each mode is developed for a specific situation. Let me explain each of them.

“Dictionary Attack” uses an in-built standard dictionary to decrypt the file. The program will find the password immediately if it is included in the vocabulary. You are given the possibility to build your own dictionary.

You should make full use of “Mask Attack” if you can remember any segment of the password. Giving some clues to the program will speed up the recovery process. You can specify the max and min length, letters (upper/lower cases), numbers, and symbols. The program will scan the specified character combinations as per your instructions.

If you remember nothing about the password, you should use the “Brute Attack” mode. It tries all the possible character combinations. Although it takes a longer time in the Access password recovery, the multi-core and multi-threading tech makes sure the time will be considerably reduced.

Owing to the intuitive layout and settings, MS Access Password Recovery is suitable for both newbies and professionals. There are no professional skills required to use this application. With its optimized technology, it runs smoothly on any Windows operating system. What’s more, MS Access Password Recovery is totally free for use.

• Click on “Add file” to import the ACCDB file to the program.
• Select one mode that fits you and adjust settings if needed.
• Press the “Start” button to begin the recovery process.
• When the process is done, a dialog will pop up and show you the password.

Microsoft Access provides an option to make the database encrypted. This helps to prevent MDB or ACCDB files from fraudulent activity. But users may forget the password and can not open the file. Using the methods above, you can remove the password from the MDB file or recover the ACCDB file password easily and quickly.
