I found my laptop from 6 years ago that my partner installed your operating system on. I have no idea what the password is. I have attempted to change it in recovery but when I try to type in a new password it wont let my type anything. I can press enter but it continues to say; 'Authentication token manipulation error' and ' password unchanged'.
I am not amazingly tech savvy, i know how to find and fix alot of problems but this type of stuff... ive done everything I could think of.
Can anybody help me?
