How to Remove Password Protection from a PowerPoint File

MS PowerPoint files (*.ppt and *.pptx) can be protected by two types of passwords: a password to open a document and a password to make changes. These are two fundamentally different file protections. Below we describe how to remove the password from the PowerPoint file for each case in detail.

1. How to Remove a Password to Open a PowerPoint File (If You Lost It)

Losing a password to open a file is the most common cause, and, unfortunately, the most difficult. The fact is that all PowerPoint files that are password protected for opening are securely encrypted with a strong algorithm. This means that it is impossible to hack a file and remove password protection from it. The only way to open such a document is to enter the correct password. When you enter the password, MS Office generates a private key and decrypts the entire document with it. A document is decrypted only if the correct password is entered, that’s it.

As you may have guessed, the process of recovering the password of your PowerPoint document is a thorough and consistent search among a huge number of options until the correct password is found. This is a long and resource-intensive process. We have collected a huge database of real user passwords to speed up the process, we can also offer brute force or a combined attack to recover your password.

The process of recovering your password on our powerful equipment can take up to 24 hours, and the recovery work is successful in more than 60% of cases. Please note that recovering a strong password is a paid service; the cost will depend on the MS Office version you have, see the Prices page. Note that a weak password recovery is free and very fast.

To start your *.ppt or *.pptx file password recovery process, upload your document to the PowerPoint Password Recovery page and follow further instructions.
