More on Passwords: Consider Using a Second Factor

Dan Conrad, writing on the IT Security Guru site, advises that, when possible, using a strong password should be accompanied by a second factor, which is known as multifactor authentication.

“Multi-factor authentication,” he writes, “is a massively important tool in double-stamping the security of your passwords. However, they are not a silver bullet. Don’t expect multifactor to protect your account when you use ‘Password1’ as your password. If the initial password is weak, this will simply encourage attackers. The account will be subjected to more attacks, so you have made the decision to leave the first security door unlocked. The best advice I can give is to use an 8+ character password AND multifactor authentication.”

Google defines multi-factor authentication as “Something you know, such as a password, passphrase or personal identification number (PIN) Something you have, such as a token or smartcard.”

When using only a password, make it a strong one with at least eight characters.

Wikipedia describes multi-factor authentication as:

“*Something the user has: Any physical object in the possession of the user, such as a security token (USB stick), a bank card, a key, etc.

“*Something the user knows: Certain knowledge only known to the user, such as a password, PIN, etc.

“*Something the user is: Some physical characteristic of the user (biometrics), such as a fingerprint, eye iris, voice, typing speed, pattern in key press intervals, etc.

“*Somewhere the user is: Some connection to a specific computing network or using a GPS signal to identify the location.
