Same here, I lost all my passwords after my PC cannot be powered up and went for servicing. the motherboard has failed so I have to replace the whole PC. After installing Avast security, I did select the Passwords (old). I was asked to login using Avast account (not the Master account). I dun remember my Avast account password as I always only use my Master account.So I tried using Google account but it gave an error and could not proceed. So I click on Forget password and managed to change. However that's when I realised all my passwords are gone. It said it detected Avast account password changed so it asked me to use another device that is sync before. I used my phone but also cannot work. Nothing happened after I entered the code it sent to my email. I think it's becos my PC already died so there is only one device left but when I click on the option where no other sync devices are available, it asked for my old previous Avast acct password. Well I would not have reset the password if I had remembered it so its now a dead end for me. What can I do?
