How Does Password Protection And Encryption Work On Windows?
Password protection on Windows involves using a series of characters to make a word that locks or restricts access to specific files or folders to only authorized persons.
The series of characters work together in the specified format to restrict access so that only people with the combination can open the specific file or folder.
When encrypting your files and folders on Windows, you can use:
- Numbers.
- Lowercase or upper case alphabet letters.
- Other special characters (e.g. “!”, “@”, “#”, etc).
Encryption involves an algorithm key or a code hiding data and restricting access to files or folders. This way, you can conceal the data in a folder or file in an unreadable format, so that it can only be decrypted by someone with a specific passcode to the folder or file.
You can choose to password-protect or encrypt your files if you share a computer with other people that you wouldn't want to be privy to the information therein. Password protection also helps create security around the files you share with others, as they can only be accessed by recipients who have the password to open them.
