I'm the same as all the other recent posts in the thread: False Blackmail attacks re porn habits.
Dozens of scam emails saying they've "hacked my email" or other, with some 6 year old password included, and have video of me beating off to some "freaky porn". Of course, I know this is false. Mostly because I installed covers over all my computer and phone cameras over a year ago. But also because the passwords are outdated, and lastly, because IF any blackmailer had such images or video, they would surely send it to you as part of the threat.
Anyhow, that was one thing. Then, recently, I got the same kind of scam with a 52sd33JI9305#^SllDk style of password, the kind that is generated by LastPass - and that got me more scared. Now I can't know that it's a 6 year old password that I don't use. Now I NEED to know if that is one of my passwords, and if so, which web account is it? I need to change my password at that web provider.
I'll do the export method for now, but there should be a built-in tool for this kind of check. Maybe not the normal search window, since that would require un-encrypted storage of our passwords, but maybe a launchable wizard, which asks you for your master password, then allows a search.
