All of my computers have the password 00000000. Apparently I have a beard.
They are located throughout America in hidden and heavily protected areas., with trip wires, snipers, a tank or two, and some big mean dogs. Also, they are buried about 1/4 mile down in concrete bunkers.
Oh, one more thing. To login, the two armed guards sitting at opposite ends of the room need to receive a message from me, then turn their respective keys simultaneously.
THEN someone gets to enter the password.
If you use 00000000 as your password under any other circumstances, yes, your computer is insecure. You might want to try using 1Password which really is a pretty good password utility. It remembers your existing passwords, generates new unguessable ones, has all sorts of browser plugins, and syncs across devices.
Of course, having super-duper complex passwords unique to each site you use is great, but it doesn’t protect you from data-theft at the actual site holding your username and password, something that happens with alarming frequency these days.
Oh geez. That reminds me. Has anyone brought food to those armed guards 1/4 mile down in the bunkers recently?
