A Comprehensive Guide to Php Multi-Factor Authentication

By on June 1, 2018

When it comes to the confidentiality of the information your website provides, one needs to be very sure about the identity or proof that the user visiting your website is the authenticated one to access the information. For this, some authentication factors work, either individually or in a combined manner to provide security or encryption to the data in different levels.

There are primarily three levels or classification of Factors for Authentication.

One is what do you know, the second is what do you have and the next is what you actually are. What the users know, is generally a password for the information. It can be a username or a token etc. “What they have” is generally associated to the possession of either an authentication certificate from the authorities or a one time password which can be used as a proof to provide users, an access to encrypted data. The final is the identity of users, which makes use of unique biological features of the users as the key to provide access to confidential information. These might include fingerprints, handprints, retina identification, face identification etc.

The Multi-Factor Authentication (MFA) works compiling these three or two of them at a time to provide layers of security through php developments.

In addition, there is a slightly less used, but important authentication factor, which is Location: These are used to prevent the use of knowledge, possession or identity at the places where one is not actually present. Hence preventing fraud. For example, the IP address is a tool to verify that a request is coming from the location of the user and hence, the user itself.

Many types of Authentications are there.

Request-based authentication makes the users supply with credentials for an authentication script. When it is authenticated, the credentials can be used for encrypting the data.

In PHP, HTTP authentication uses headers. It triggers the web browser to open a dialog box for user possession and password feed. Moreover, there are two basic ways authentication is done. Surely, one is better than the other. These include Basic Authentication and Digest Authentication. The latter one allows the encryption of the credentials too, which add to the security of data. Digest Authentication is better than the Basic one.

A term called Third Party Authentication is also present. This means providing credentials to a trusted third party which either provides a certificate of authentication, declares the user identity as the validated one. Thus helping in easy access to information and less complexity in the process of authentication, each time we visit the website.

Various technologies are available to provide your data with best of security layers. Each of these technologies is based on one of the three factors of authentication. Software tokens are one of them, which include the generation of unique one time passwords or PINs which are the Personal Identity Numbers. These are software generated single-use codes which fall under the category of Multi-Factor Authentications in mobiles. Another one is Security tokens falling under the Possession Factor of Authentication. Some hardware equipment like swipe cards or USB Devices are provided to the user which contain their unique ID and passwords and every time they show them up to sensors, they can get access to encrypted information or networks. But it is less efficient than software tokens. Mobile Authentication techniques and Biometric Authentications are also there which are also an important security part.

So, adding MFAs to your Php websites is a way to keep limited and safe access to your data and adds to the productivity of your site and users.
