Relying alone on passwords for secure authentication is no longer sufficient, in fact, considered among the weak links in cybersecurity. Multi-factor authentication and its best practice solve this problem as it can effectively block more than 90% of account attacks. Researcher says 80% of data breaches occur due to weak passwords, stolen credentials, or common passwords. MFA can solve this problem, as it combats attacks like dictionary passwords, brute-force, phishing, etc., using common, stolen, or weak credentials. Organizations using password-based authentication can implement MFA as their first step toward better security, and while implementing it, they should ensure multi-factor authentication(MFA) best practices.

factor Authentication (MFA)

2. How does the vendor provide support for evolving threat
vectors?
Choose an MFA Vendor
To choose right MFA vendor, Organization should get
answers to these questions-
Can the vendor’s MFA solution scale effectively as your
business grows?

Does the vendor provide built-in compliance adherence

3. Users may face MFA fatigue or might try to
work around it if the MFA solution is difficult
to use. One way to ensure ease of use is to
provide them with various authentication
factors to choose from.

4. Consider all types of users while locking the
authentication factors for your application.or a
variety of users, it is not good to only have one
authentication factor for all.
Utilize variety of
authentication Factors
Here are a few mostly used factors for MFA:
Email Link
Email OTP
SMS OTP
Phone Call
Biometric

5. Most researchers believe that the weakest link
in the security chain is the user. Therefore, no
amount of parameters can ensure better
security if users are not using it effectively.
Educate Users on MFA
The following can be the parameters to educate
users in the initial phase:
Why should the user care about adopting MFA?
What’s the final goal of adopting an MFA?

6. Don’t limit multi-factor authentication to specific
user roles i.e. all users should be required to use
multi-factor authentication for any account access
across the organization, regardless of the
sensitivity of the information. This ensures that no
user account is left unprotected.
Use MFA across Organization

7. In some scenarios, constantly asking users to
complete MFA for authentication can be a
frustrating experience. In such cases, adopting
adaptive or step-up authentication is a better
approach. Adaptive MFA uses contextual
information to determine whether to request
another factor for user authentication or not.

8. Combine MFA with SSO
Single sign-on authentication provides a great
user experience, and combining multi-factor
authentication with SSO can deliver a smooth user
experience and strengthen security.

9. Although MFA can provide additional security, it
can also be vulnerable to attacks if not
implemented correctly. As a general MFA best
practice, organizations need to ensure that their
MFA solution is configured securely and that
users are aware of how to use it effectively.

10. Security threats are always evolving; thus,
organizations should periodically re-evaluate
MFA to ensure that implemented MFA meets
both users’ and organizations’ needs and, at the
same time, fulfilling the refined security
requirements too.
