One of my co-workers/clients had password trouble yesterday, so I had to assist her through a reset.
She needed to set a new password, and asked me to just think of something. There was a picture of a dolphin above her desk, so I suggested "dolphin", plus a couple of characters to make it complex enough for our system to accept. She thought that was a great idea.
This morning, something was wrong, and she couldn't log in. "Oh, these stupid computers..." etc.
I sat down to do some troubleshooting and noticed she had written down her password on a Post-It: "dolpin###"
"Um... you've written this down incorrectly. "Dolphin" has an H in it."
"Yes, after the P."
"Are you sure?"
I wrote it on a fresh Post-It, and she peered at it. "Are you sure this is right? It doesn't look right..."
