I'm a new FiOS Internet customer and I saw that e-mail passwords have to be at least 6 characters, including one letter and one number. OK, so I can't use the password I used on my old account.
But when I chose a password composed of an English word plus two numbers it was rejected as too easy to guess.
Then I chose one composed of a foreign word plus numbers. It, too, was rejected for the same reason!
(At this point I want to mention that I once saw network correspondent John Roberts at a computer equipped with a password-cracking program and it guessed his password in a few seconds, and the password was "konnichi-wa" ("Good morning" in Japanese).
Still, my 2nd rejected choice should have been as unguessable as my final choice (which I won't hint at here)
