I am using Ubuntu as my main OS. I am not an expert at all, and found myself not able to login to my pc, since I forgot my password. But then I found out that it is super easy to reset the password. That is a big concern for me. I use google chrome to save all my passwords and have it to autologin to my google account. I thought that was safe as long I had enabled password login. Even if my computer got stolen, without my password, the bad guys will not be able to login to my pc.
So my question is. How do I make my computer safe again. Do I have to encrypt my pc since as far as I understand, resetting root password will not change the encryption password.
