Zip files aren’t the ultimate solution for optimal file security. But password protection is the first line of defense when hackers get their hands on your file. It’s like someone finding a treasure chest but not being able to open it without the proper key.
How To Password Protect A Zip File
Password protecting a zip file depends on the use case that you’re seeking. Whether somebody else has to access the file or it is only you. It also depends on whether you want to install a third-party app or not. Read along to find out how you can password protect a zip file.
Password Protect A Zip File in Windows
Built-in Windows Encryption
This approach works on Enterprise, Education, and Pro versions of Windows. It is not available in the Home version. The good thing about this approach is that you don’t need to involve any third-party apps. Once you encrypt the zip file, it is accessible only if you logged in from the same user who encrypted it. This is why you will see no change when attempting to open the zip file. But, if you log in to your PC using a different user, the file is inaccessible. One key thing to note here is using this method of password protection secures the file for a single user. It means you cannot share it with anyone else. This is because the file won’t open on anybody else’s Windows PC. It won’t open on your PC either if you log in under a different username. Thus this file is now tied into your user account. If you lose access to it, you won’t be able to recover your zip file.
Third-party Apps
Third-party apps are only tied to the passwords they create during compression. Even if you lose access to the user account, you can still recover zip file contents. This also means that if the password is leaked, anyone can open the zip file’s contents. They don’t even need to open the zip file on your PC.

You can still delete the password-protected content of a zip file.You can still add insecure and malicious code to the content of a zip file.You can delete and replace the secure content without entering a password.
