What is Authentication?

The terms are frequently utilized in conjunction with one another regarding security, especially about gaining access to the system. Both are very crucial topics frequently associated with the web as key elements of its service infrastructure. Nevertheless, both the terms are very different with completely different concepts.

While it’s true that they’re frequently utilized in the same context with the same tool, they’re unique from one another. Authentication means confirming your very own identity, while authorization means granting access to the system. The system determines regardless if you’re what you say, you’re utilizing your credentials.

A user name and password usually do authentication, sometimes in combination with authentication factors, which pertains to the various ways to be authenticated. Authentication factors determine the system’s various elements to verify one’s identity before granting him access to anything from accessing a file to requesting a bank transaction.

A user’s identity can be determined by what he knows, what he’s, or what he’s. Regarding security, at least two or all the 3 authentication factors must be verified to grant someone access to the system.

Based on the security level, authentication factors can differ from one of the following: Single Factor Authentication Its simplest authentication method commonly relies upon a simple password to grant the user access to a certain system like an internet site a network.

The person can request access to the system using only one of the credentials to verify his identity. The most typical example of a single factor authentication will be login credentials requiring a password against a username. Two Factor Authentication As the name suggests, it’s a two-step verification process that requires a user name and password and something only the user knows to guarantee an additional security level, like an Automated teller machine pin, which only the user knows.

Utilizing a user name and password together with an additional piece of classified info makes it practically impossible for fraudsters to steal valuable data. Multi-Factor Authentication It’s the most advanced authentication method that uses two or more security levels from independent authentication categories to grant the user access to the system.

All of the factors should be independent of every other to eliminate any vulnerabilities in the system. Financial organizations, banks, and law enforcement agencies use multiple-factor authentication to safeguard their data and applications from potential threats.

For instance, whenever you enter your Automated teller machine card into the Automated teller machine, the machine asks you to enter your pin. Once you enter the pin correctly, the bank then confirms your identity that the card really belongs to you and you are the rightful owner of the card.
