Fellow Mad Props blogger Crucible recently discovered the enhanced security provided by using a passphrase rather than a simple password. A passphrase is a sentence or phrase that you use as a password - it's much longer than your average password and thus much, much harder to crack.

So he has changed to using a passphrase as his network login, and also on various web sites he is a member of.

In doing so, however, he has discovered something awry with yahoo's sign-in system. Check out his post. Interesting stuff.
