Multi-factor authentication is a form of authentication that requires more than one piece of information to verify an identity. Learn more about MFA here: https://bit.ly/3JN9Elx

1. What, Exactly, is Multi-Factor Authentication,
and How To Use It?
Introduction
Multi-factor authentication is a security feature used by businesses to ensure that the
consumers coming to their websites are actually who they say they are. MFA is done by
providing at least two pieces of proof or evidence to state an identity, like, say:
1. Something only they would know.
2. Something that only they possess.
3. Something that they are.
Multi-factor authentication (MFA) is a type of authentication that requires more than one of the
following: something you know, something you have, and something you are. MFA works in this
way because if one factor is hacked by an attacker or invalid user, the chances of another factor
also getting compromised are pretty low. That is why MFA authentication requires multiple
factors, and this is how it provides a higher level of API security to consumers' identity data.

2. Why is MFA so Important
Secure passwords remain the most common authentication method of online identity, but they
provide very little protection. Consumers often make it simple for attackers to steal their
credentials by choosing weak passwords or using the same passwords for multiple applications.
One of the biggest problems with traditional user IDs and password is that they require email
and password login and database maintenance.
It does not matter if they are encrypted or not; once the database is captured, it gives the
attacker access to every detail, like geographical locations, consumer interests, transaction
patterns, etc. Multi-factor authentication is imperative to use because even if the attacker gets
access to the database, they still need to pass other security checks.
How Does Multi-Factor Authentication Work
Multi-factor authentication (MFA) is a security feature that requires multiple verification methods
to verify the identity of a user. One of the most common types of MFA is one-time password
(OTP) authentication. In this type of authentication, an OTP code will be sent to your mobile
device by SMS, and you can use it to log in once only.
There are three main methods on which MFA authentication heavily relies, those being:
1) Knowledge-based Authentication
Knowledge-based authentication involves questions that only you can answer, such as "What is
your mother's maiden name?" or "What is your child's name?
2) Possession-based Authentication
Possession-based authentication verifies possession of something only you would have access
to, such as a mobile phone.
3) Biometric Authentication
Biometric Authentication verifies that it is actually you making the attempt to log in by using a
fingerprint or retinal scan.
Types of Multi-Factor Authentication
1. SMS-Token Authentication
A relatively straightforward measure to implement, especially for consumers and the general
public, this check most often consists of a text message containing a PIN number. This PIN is
then used as a one-time password (OTP), usually in addition to traditional

3. username-and-password verification. If you're concerned about security for your customer's
mobile devices, adding an extra layer of protection such as this can be a good idea.
2. Email Token Authentication
This method is identical to SMS tokens, but the code is sent via email. Since not everyone has
their phone with them all the time, it's a good idea to offer this option as a backup when your
customer misplaces his or her mobile device. It can also be convenient for accessing an OTP
from any platform that can receive emails.
3. Hardware Token Authentication
Hardware tokens are among the most secure authentication methods available as long as the
consumer retains possession of the key. This method is more expensive than other options but
can be cost-effective when providing dongles to high-value customers. Business customers tend
to be more willing to go the extra mile to use a hardware token; however, it's still not a good idea
to make them compulsory for anyone but at-risk customers, such as banking, insurance, and
investment clients.
4. Software Token Authentication
When customers use a hardware token or an application on a mobile device to generate
one-time passwords, they are giving their business the same level of security as if they were
using a hardware token. This can be tied in with services like Google Authenticator that rely on
passwords generated by a smartphone or tablet.
Getting customers to use these types of third-party solutions can help encourage them to use
multifactor authentication for more of their services outside of your business, thus increasing
their overall security. It also makes a great alternative to carrying an additional dongle to attach
a hardware token to a mobile device.
5. Biometric Authentication
People with a smartphone, computer, or tablet can use biometric authentication to confirm their
identity as part of multifactor authentication. Biometric ID verification tends to be less hassle
than typing in an OTP, so customers find it less aggravating to use it frequently. The lower
friction makes it an ideal option when extra checks are unavoidable.
Benefits Of MFA:
The benefits of multifactor authentication are becoming more widely accepted as an essential
part of the modern experience, and consumers expect all well-managed organizations to have
it. Multifactor authentication is quickly becoming a standard offering from the biggest tech

4. companies that we deal with today. Failing to meet these expectations leaves you at risk of
losing clientele to companies that are using CIAM and MFA to keep their data from harm.
1. Better security: It provides additional protection for consumers and employees in multiple
layers of security.
2. Boosted conversion: A streamlined authentication process keeps productivity high and
leads to increased conversions.
3. Improved customer trust: Due to extra security checks, consumers are assured about
the data they provide.
4. Reduced operating costs: The more layers there are in an authentication process, the
less likely an intruder will be able to break through them all before being detected.
5. Achieve compliance: Specific to your organization to mitigate audit findings and avoid
potential fines.
6. Increase flexibility and productivity: Removing the burden of passwords allows
employees to focus on other tasks while still being able to access vital resources when needed
Conclusion
Multi-factor authentication is an excellent way to balance security and customer experience. It is
not only one of the best ways to secure your login process, but it also shows your customers
that you care about their security and takes it seriously. This feature increases the consumer's
account safety. Finally, before implementing any functionality on your website, analyze and
consider all possible angles.
