Decrypt / Recover Windows 8 Pin Code and Picture Password Instantly
In this tutorial we'll show you how to decrypt and recover the original Pin code and Picture Password in Windows 8/8.1, without brute-forcing them. Both Pin code and Picture Password are authentication methods based on a local user account. During setting up a Pin code or Picture Password, you'll be prompted to enter the traditional text-based password. The problem is that Windows 8 will then store your Pin code / Picture password as well as the original text password in plain text.
Mimikatz is a free open-source tool to recover this plain-text password, it saves you time and power needed to brute force a 16 character NT/LM password during pen-testing or tech work. Follow this tutorial and you can extract the Windows Pin code and Picture Password in plain text.
Note: Mimikatz needs admin privileges to work properly. If you couldn't log on to Windows 8 as administrator, you can reset the forgotten local administrator password or Microsoft account password with PCUnlocker Live CD/USB drive.
