The day continues with a Mac, and two desktops all running side by side using a software KVM your single keyboard and a mouse empowering you with the might of a dictator running a small nation. Check in that source code patch there, respond the Elgin who’s inquiring about when your team’s next release will go live, swing the mouse to the far left (into the connected Mac) to make sure you’re not late for your daily stand up, swing your mouse back to the right (across the WinXP desktop) into Linux land where focus follows your mouse cursor and begin the login process to the production system. What’s that blinking slightly behind your terminal window? Oh that’s your chat window where all of your buddies are hanging out discussing which bar they’re going to hit this weekend! ignore that for now as you sip from your coffee mug and delicately place it back on the desk only slightly nudging your high precision optical mouse. Lets type the old password for the production server, which also happens to be the same password for your email, your online bank account, your employee payroll access center, and about half a dozen other highly sensitive places that you don’t care to be banned from simply because your memory has the capacity of an old 386 machine from the late eighties after an install of Doom. We type fast because we’re professional and we know what we’re doing. We quickly mash the enter key as a reflex to the muscles trained habit of typing the same password 647 times per day. We only realize after the chat window comes to life that the slight nudge from our coffee mug was just enough to move the cursor off of the terminal window and onto the chat window where “focus follows mouse pointer” (because you’re such a clever KDE desktop nut). We have now given the secret keys to our bank account, email, company secured servers, and plenty of other secured locations to the rowdy bunch of compadres on the other end of your connected ICQ Instant Messenger Network.
Well done genius! You not only have the joy of tracking down and remembering all of the servers and websites that your now exposed user credentials belong to. You also have the honor of resetting various browser and other software for the next 27 days and tracing bugs due to authentication failures where these same credentials were hard coded in local text files among other places. So if you wanna suck at software, use the single user id password system. Exposing it to the world over an IM or an email goof only hurts twice as much as leaving your gas oven on during a vacation to Tahiti.
