We happen to sign up for so many services and accounts that it becomes a problem to remember all the passwords for each of them. To avoid this problem most people wish to keep the same password for all their accounts.
In this Tip of the Week, TS advises you to never keep the same password for all your online accounts and services. Reusing passwords (using the same password for more than one system) is similar to carrying one key that unlocks your house, your car, your office and your safety deposit box. One lost key could let a thief unlock all the doors. Always choose different passwords for your home computer, office computer, different e-mail accounts, bank accounts etc.
Keep in mind that – if you reuse passwords, your password is only as secure as the least secure system on which you have used it. Therefore it is a better and safer habit to keep different passwords for different accounts.
