Recently we have heard a lot of talk about authentication and multi-factor authentication. Well, we usually login to systems by entering a USER-ID and a Password. This is called authentication. You are identified to the systems by your USER-ID, which remains the same, and by a Password, which you should change on a regular basis. The password that you create is associated with your USER-ID. Your password should be complex and use upper and lowercase alpha characters, numbers, and any special characters your system allows. I make it a policy to change my password at least every 90 days. I have a calendar entry in Outlook that reminds me to change my password every 90 days.
Most systems require authentication by USER-ID and password. However, on newer and improved systems we can use Multi-factor authentication if it is available by providing three ways of authentication: First, by supplying information we Know, such as a password or personal identification number, Next, by using something that we Have with us (smartphone, a security token or smart card), or by giving the system something we Are, something unique to Us (What we are) like a physical part of us (our voice, our eyes, or our fingerprint).
With the release of the newer smart Phones we have the ability to do multi-factor authentication using the bio-metric Touch ID fingerprint sensor built into the smart phone home button. This used in addition to USER-ID and Password is called Multi-Factor Authentication.
Finally, lets strengthen the passwords we use for authentication. Right now let us all just change our passwords on a regular basis and make them as complex as possible. Make Your password at least ten (10) characters, the longer the better, Your password should be complex and use upper and lower case alpha characters, numbers, and any special characters your system allows.Here is an example of a good password:
Notice the repeating special characters at the end. The length is 15 Characters and all combined this can really enhance your password from being hacked. Remember, the longer, the better, and the more complex, the better. “Be cyber wiser” and change your password(s) as frequently as possible..
