Password protection types in Microsoft Excel

Microsoft Excel offers several file protection options: strong protection against unauthorized access (“Password to Open”) and weak protection against editing (all other types of password protection).

  1. Protection from unauthorized access (strong protection):
    • Password to Open
  2. Protection against accidental editing (weak protection):
    • Password to Modify
    • Excel Sheet Password
    • Workbook Password
    • Excel VBA password

Once you set an “Password to Open”, all data in the Excel file will be encrypted which makes it impossible to unlock the file without knowing the password. To find a password (search or recover it) takes time and requires special software to unlock an Excel password. The search time depends on the Excel format and complexity of the password.

However, other types of passwords do not encrypt Excel file data. They only lock certain actions. So you can actually open an Excel file and work with the data. You will only need a password to edit data or save changes. Whichever version of Excel you are using you can always recover or remove any weak protection password in a matter of seconds.

Password protection in Excel is actually a much-needed and useful thing. But once you no longer need it, all those passwords become irrelevant, irritating and eventually get lost.

Not an issue. Let's try and unlock our Excel file and simply remove the passwords.

How to Unlock Excel File When You Know the Password

When you know the password, unlocking an Excel file is similar to locking it: you enter the password, delete it, and save the file without password protection.

Let's see how it works with Excel 2016

Password to Open

1. Start Excel, click on “Open” in the left menu and select the file

And that’s it. Now you have deleted the “Password to Open” and decrypted the data. You won't need a password the next time you open the file.

Password to Modify
