It's a contradiction, it seems: if a website cannot, and should not be able to tell you what your password is, how do they know you've typed it correctly at sign-in time?

Understanding this will help you know what to look for the next time your email address appears in a large-scale data breach.
How Do Websites Keep Passwords Secure? has the scoop.
Also this week:
- Trouble emailing large files? You shouldn't try, because you don't have to any more.
- "Mailbox Unavailable"? It's email's version of "something didn't work".
- You could be using BitLocker and not even know it. If true, you'll want to do this . . . soon.
One of my Ask Leo! videos took off a couple of weeks ago, and it led to a great discussion on backing up, archiving, the difference between 'em, and the best implementation for the latter. Turns out Gary and I independently arrived at the same conclusion and are doing roughly the same thing. Cool stuff, some self-promotion, and a test of . . . video? Yep, I tested an approach to recording my side of the podcast in video, and it was good enough to share. TEH 141: Backups, archives and possibly Pluto.
See you next week!
