When you wanted to sign-in, a gatekeeper application would ask you for your password. In the early days of computers and mainframes, passwords were stored in a database as plain text. Once you finish reading this you should have a working knowledge of hashing algorithms, how password cracking works and what “strong password” really means.

In this article we’re going to explain how computer systems have evolved in the way they process your password, how modern online applications do authentication and why it’s important to choose a strong password. Most of us see them as an inconvenience – something you have to tolerate to be able to use a service you need access to. that can be validated by a social network graph or chain of trust. a neurological trait that can be scanned by an MRI. at a physical address able to receive snail mail. Other attributes used for authentication: A few other attributes that you occasionally see used for authentication are: Other biometric systems include retinal scans (the blood vessels at the back of the eye) and iris scans (the colored part of the eye). Unless you steal someone’s index finger you won’t be able to access our data center, even if you’ve stolen a valid swipe card. To access our data center we have to put our index finger on a fingerprint scanner after swiping a card. Something you are: This is where biometric security comes in.

Something you have: Examples are a swipe card to access a secure area, a code sent to your cellphone as part of a login process (to prove you have your cellphone) or a SecureID token that provides a constantly changing code you need to enter to gain access – all are something you have that can be used to authenticate yourself. Something you know: Examples of this are your good-old password, bank card PIN or a safe-word when the alarm company calls your home these are all examples of using something you know to authenticate yourself. However, passwords are not the only authentication mechanism.

Passwords have been the default method of authentication for as long as most of us have needed to prove to a computer that we’re allowed to access it. An authentication mechanism (or method) is a way for you to prove that you’re allowed to access something. In this article we’re going to explore different authentication mechanisms.
