Part 2: Unlock Password Protected ZIP Files Online

There are many online sites to crack password protected ZIP files for free, among which LostMyPass is one of the more common online tools that allow you to decrypt ZIP files online without using any software.

Decrypting ZIP files through online websites has a relatively high security risk.

If your ZIP file is sensitive, this method is not recommended.
