Computers are cold, unforgiving machines, especially when it comes to usernames and passwords. Nothing is more annoying then trying to sign in with a bad password. Say you have it written down and you type it in exactly as it is written, but no dice! The precision of a computer is often the issue when a website or system does not let you log in. For humans like you and me, it’s quite easy to confuse letters with numbers, or caps with no caps.
Having your passwords written down somewhere is not the best idea, but if you must do it make sure what you have is written correctly. Zeros and the letter O look quite alike when written by hand, as do ones and the letter l. Below is a written password with little to no difference between letters and numbers.
The same thing applies to usernames… While capitalization does not matter with a username, it matters with passwords. Below is a written password that HAS a difference between letters and numbers. Look at the letter o next to the zero in Book. The slash is pronounced and makes confusion a non-issue. The same goes for the 5 and the letter S. Also notice the number 1 where an l (L) should be.
To conclude, make note of these trouble letters: L, S, O and their bothersome number counterparts: 1, 5, 0 and you will be well on your way to Sign-On Bliss!
