LostMyPass is excellent for instantly removing sheet/edit protection from any modern Excel file.

It’s a solid choice for non-technical users who prefer a GUI over command-line tools like hashcat.
Rating: 8/10 (loses points for Windows-only, paid model, and no cloud fallback).

LostMyPass is an online password recovery service designed to help users regain access to encrypted Microsoft Excel files and other document types. It operates as a web-based tool, meaning it does not require software installation and works through any modern browser. Core Features of LostMyPass for Excel
The service specializes in recovering "open" passwords for Excel files (including .xls and .xlsx formats) using three primary recovery methods:
Weak Password Recovery (Free): This feature attempts to crack passwords using a large database of common passwords (around 3 million). It is typically fast, often completing within a few minutes.
Strong Password Recovery (Paid): A more advanced feature that uses a significantly larger dictionary (over 20 billion passwords) to find more complex combinations.
Brute Force with Mask (Paid): This allows users to provide partial information about their lost password (such as length or known characters) to narrow the search and increase efficiency.
Cloud-Based GPU Processing: To speed up the recovery of complex passwords, the service utilizes geographically distributed clusters of high-performance GPU servers.
Brute Force Calculator: A diagnostic feature that estimates how long it will take to unlock a specific file based on its type and suspected password complexity. Key Limitations & Security Considerations
While LostMyPass is highly regarded for its ease of use, it has several constraints:
File Size Limit: The maximum upload size for an Excel file is 100MB.
Privacy Risks: Because it is an online service, files must be uploaded to their servers, which may not be suitable for highly sensitive or confidential data.
Internet Dependency: A stable internet connection is required for the entire upload and recovery process.
For users who prefer local alternatives, software like PassFab for Excel or Passper for Excel allows for offline recovery on Windows or Mac systems.
LostMyPass is a specialized online service designed to recover lost or forgotten passwords for Microsoft Excel files using cloud-based GPU clusters. It is frequently cited as a primary option for users who cannot access encrypted workbooks and prefer not to install local software. Service Overview
LostMyPass offers three distinct recovery levels based on the complexity of the forgotten password:
Weak Password Recovery (Free): This checks your file against a database of approximately 3 million common passwords. It is usually instantaneous and has a high success rate for simple or reused passwords.
Strong Password Recovery (Paid): A more intensive search using massive dictionaries. It typically costs around $59 for a successful recovery of an Excel password. lostmypass ms excel password recovery
Brute Force with Mask (Paid): Used when you remember certain characters or the length of the password. You can use their Brute Force Calculator to estimate how long a recovery might take based on your specific parameters. Key Features
Speed: Paid recoveries often take only a few hours due to the use of high-performance GPU servers that are significantly faster than a standard home PC.
Compatibility: Supports various Excel formats including .xls, .xlsx, .xlsm, and .xlsb.
High Ratings: The service holds a high reputation on platforms like Trustpilot, often rated near 4.9/5 based on thousands of reviews. Security and Usage Considerations Before uploading a file, consider the following:
Data Privacy: Since it is an online tool, your file is uploaded to their servers. While they claim professional data handling, highly sensitive financial or personal data may be at risk.
File Size Limits: The service typically limits uploads to 100MB.
Alternatives: If you only need to remove Sheet Protection (not a password to open the file), you can often do this manually by changing the file extension to .zip and editing the internal XML files, which costs nothing and keeps your data local.

Upload: You upload the encrypted .xls or .xlsx file to their secure server.
Processing: The automated system attempts to match the encryption hash against known passwords.

Confidentiality: The site typically claims to delete files from their servers shortly after the recovery process is finished.
Encryption Support: It supports various versions of Excel, including legacy formats and modern AES-128/256 bit encryption. Manual Alternatives
If you are trying to unprotect a specific sheet (rather than the whole file) and don't want to use a third-party service, you can sometimes manually remove the protection:
XML Editing: Change the file extension to .zip, open the xl/worksheets/ folder, and edit the specific sheet's XML file to delete the tag. Disclaimer: Use password recovery tools only on files
Standard Unprotect: If you have the password, simply go to the Review tab and select Unprotect Sheet or Unprotect Workbook.

Strong Password Recovery (Paid): For more complex passwords, this option utilizes a much larger dictionary of over 20 billion entries. It has a significantly higher success rate of around 61%. Most reviews note that users only pay if the recovery is successful.
Brute Force with Mask (Paid/Custom): This method is used for specific cases where the user remembers partial information about the password (e.g., it starts with "A" and is 8 characters long).

Title: Solved: Using LostMyPass to recover lost Excel password – My experience & warning
Post:
Hi everyone,
I recently locked myself out of an old Excel workbook (Excel 2016, .xlsx file) and came across “LostMyPass” in my searches. I know a lot of people land on this tool, so I wanted to share what actually happened, what worked, and what didn’t.
Short version: LostMyPass is a legitimate tool for removing the “open password” from older Excel formats (.xls), but it’s not a magic cracker for modern encryption.
Here’s what you need to know:
My result: LostMyPass failed to recover my .xlsx password after 3 days of running. I ended up using a different method (restoring from a backup + zip trick for sheet protection, not file-open).
⚠️ Important warnings:
The one legit free trick for SHEET protection (not file-open): Title: Solved: Using LostMyPass to recover lost Excel
Final advice: Before trying any recovery tool, double-check if you need the file-open password or just sheet/workbook modification protection. For modern Excel, no consumer tool guarantees recovery. Back up passwords in a manager next time.
Has anyone actually succeeded with LostMyPass for a 2020+ Excel file? Curious to hear.
Excel password protection comes in two main types:
| Type | Purpose | Security Level | LostMyPass Approach | |------|---------|----------------|----------------------| | File open password | Prevents opening the file | Strong (AES-128, AES-256 for modern Excel) | Brute-force, dictionary, mask attacks | | Sheet/workbook protection password | Prevents editing cells, sheets | Weak (XOR-based obfuscation up to Excel 2019) | Instant removal (seconds) |
Key point: LostMyPass can instantly remove sheet/workbook protection passwords (even from recent Excel versions). For file-open passwords, it uses GPU-accelerated attacks.
LostMyPass offers three primary attack modes. Your choice will determine success or failure:
| Attack Type | Best Used When... | Speed | | :--- | :--- | :--- | | Dictionary Attack | You usually reuse common words, names, or phrases. | Very Fast | | Mask Attack | You remember parts of the password (e.g., “starts with ‘Blue’, ends with ‘!’, 8 chars total”). | Fast | | Brute-Force | You have no clue, but the password is short (max 6-7 characters). | Very Slow (days/weeks) |
Pro Tip for LostMyPass Users: Do not start with brute-force. Begin with a custom dictionary that includes your known passwords, company name, and the current year.
Forgetting an Excel password is a uniquely frustrating experience. You are not locked out of just a file—you are locked out of hours of work, critical data, and potentially vital business decisions. The good news is that lostmypass ms excel password recovery is a proven, legitimate solution for lawful owners.
Final Verdict: LostMyPass is an excellent choice if you have some memory of the password (length, pattern, or common words) and a decent computer with a GPU. It is not a magical instant-unlock button, but it is one of the most effective tools in the market.
Your next step: Download the free trial of LostMyPass, load your locked Excel file, and run a dictionary attack with a custom wordlist containing your known passwords. You might be surprised how quickly it works.
Remember: Once you are back in, remove the password and modernize your security practices. A password manager is cheaper than a week of lost productivity.
