How can I recover Windows 10 IoT password for Raspberry Pi 3?
I also thought I forgot the password, but I found I never changed it. The default password is 'p@ssw0rd'. The key to remember is you have to include the machine name in the username field. For example... 'minwinpc\Administrator'
To answer the specific question though, I don't believe you can recover the password if you have changed it and forgot it.
