What is MadPassExt?

Windows uses Data Protection API to secure stored information and sensitive data, such as your passwords and credentials, private keys, as well as other confidential data generated, either by the operating system or an app. The Microsoft account that logs in with Windows generates the DPAPI key. This key is needed if you are trying to recover passwords encrypted with DPAP. However, getting it might be tricky, especially for novices.

MadPassExt is a utility application that offers a simple solution. As mentioned, it works as a password recovery tool, allowing you to decrypt and extract the secret DPAPI password for your Microsoft account. As mentioned, the app is installation-free and easy to use. Once launched, it prompts you to input the password for your Microsoft account. You can also type the filename or folder of your Microsoft account cache file.

Click the Decrypt Microsoft Account Cache file button to decrypt the cache file. You should see the secret DPAPI password if you provide the correct password. You can then copy the password to the clipboard and use it wherever you need to. Note, however, that you have to run the app as an Administrator for it to work. Conveniently, there is a button to re-launch the tool as an administrator.

Get your DPAPI password with ease

Overall, MadPassExt is a tool that can come in handy when you want to obtain the DPAPI password associated with your Microsoft account. It may have a simple interface but the app does the job well, decrypting and extracting the secret password in minutes. It also allows you to copy it and use it as you please. However, it requires administrator privileges and a Microsoft account password to work.
