Hi Martin, I have also had this same issue with the programme suddenly asking for a Master Password, which I don't ever remember setting. I do have an authorisation password I enter whenever I want to go and change a setting, for instance - and that still works perfectly fine. I thought that was the Master Password.
Anyway, this issue arose when I noticed an option in privacy settings which allowed the user to turn on the requirement for a password to be entered if they wanted to enter...for instance, to access saved passwords. Of course when I read the words 'Master Password', I thought it meant the authorisation password I use for any setting changes. BOY, was I wrong. The second I turned on the choice to protect my saved passwords, with a password...I was instantly presented with a Master Password entry box. I entered my authorisation password, and boom...no luck. I have been locked out ever since.
I have been all over the forum looking for help. I have attempted to uninstall the passwords component, then reinstall - that didn't work. I attempted to uninstall the whole Avast suite (OMG, btw)...that didn't work - twice. It is driving me crazy. I don't care that I can't recover my passwords locked in the password component - it is possible to simply reset them one-by-one as I go to each site. What I really want to get working again though is the ability to save passwords on sites and once and for all, get rid of that weird Master Password popup!!
Please help. How do can I do this? What am I doing wrong in the uninstall that it doesn't reset to default (without the requirement for a Master Password)?
Looking forward to your help on this.
