Password
Do all of your passwords seem to expire at the same time? Yeah, me too.
Things will be rolling right along and then my laptop will ping with an "update" reminder to choose a new password. Which would be ok if every other entity in my life didn't require a similar adjustment.
Accessing email, paying bills, even reserving a book at the library requires a password. Which means every few months I must create a new combination of letters, numbers, and symbols that are both memorable and opaque. It's like trying to solve a crossword puzzle using invisible ink.
Perhaps this obsession with security has kept my personal details protected. But I fear the only person who can't figure out my passwords is me!
"Treat your password like a toothbrush. Don't let anyone else use it and get a new one every six months." – Clifford Still
