Protecting important documents with a password is a wise security option that anyone should apply. However, what if you accidentally forget them? Do not worry! If you're using Microsoft Office, you can immediately use the following powerful password recovery tools:
Note: You should only use these tools to remove passwords from personal documents, using it on other documents is illegal.
Microsoft Office password recovery software is divided into two categories: eraser and recovery tool. Both are useful but their uses are a bit different.
Since Office 2007 , Microsoft aims to use 128-bit AES encryption. The process of breaking 128-bit AES code is extremely time consuming. If the password is strong enough, the file is still safe, even if AES-128 is compromised.
Assess the strength of passwords in each version of Microsoft Office:
- Microsoft Office 95 : Weak encryption converts passwords into 16-bit encryption; Can decode instantly
- Office 97 and 2000 : Encryption length up to 40-bit; Instant decoding
- Office XP and 2003 : The encryption length is still 40-bit but Microsoft adds the option of protecting custom encryption algorithms; Decoding speed depends on that algorithm
- Office 2007 : AES encryption, SHA1 integration; Password recovery difficult
- Office 2013 : Still using AES-128, but updated the hash algorithm to SHA-2; use SHA-512 by default; Extremely difficult to recover passwords
Even if you set a super-long password in Microsoft Office 95, it will only have a small effect on the fragile encryption algorithm. Obviously, Office 2013 provides stronger file protection despite weaker passwords because it possesses encryption and a stronger security algorithm.
1. Free Word and Excel Password Recovery Wizard

The Free Word and Excel Password Recovery Wizard is one of the first options to consider. This program tries to unlock the file with brute force attack or dictionary attack (dictionary).

Word Password Recovery Master is another useful free password recovery software. It supports a wide range of Microsoft Office versions and is capable of handling many different issues.
However, this mighty statement of the publisher is not entirely accurate. During the trial, it was unable to recover or remove the basic password created by Office 2010. Therefore, this program may not work in a newer version of Office. However, Word Password Recovery Master erased Microsoft Office 2003 password extremely easily.
Note, the software does not support custom encoding types. It is designed only to handle the default encryption of Microsoft Office.

Elcomsoft Advanced Office Password Recovery (AOPR) is a professional Microsoft Office password breaking software. Therefore, you need to pay if you want to own the full benefits of it. 49 USD for Home Edition purchase is the cheapest option.

Using a password-breaking GPU is more effective. If you really want to get rid of them, upgrade to Standard Edition ($ 99).
Worth the price, AOPR has many great features, allowing custom dictionary, character set, password length as well as running dictionary, brute force attack. Also, if you know anything about your password, you can "fake" the information to continue the process.
