Read the article to find out how multi-factor authentication (MFA) is a major win for the effective security of your data.
What is MFA?
Multi-factor authentication is a process that uses multiple factors to verify user identity before granting access to an account or data. Classic password authentication only requires a single factor for verification whereas multi-factor authentication uses at least two. Web-based and mobile solutions mostly use a password together with a time-limited token sent to the user, but there are a wide range of ways to implement MFA.
The main benefit of MFA is to boost enterprise security by asking users to supply more than just a username and password to gain access. Usernames and passwords are definitely important, but they are easy to hack and steal. Using multi-factor authentication with a fingerprint or physical key boosts the level of effective protection against hackers.
What are the benefits of MFA?
Efficient data security
Multi-factor authentication allows you to boost your security by adding an extra layer of protection in addition to a password to reduce the risk of unauthorised access and reinforce defence against various kinds of attacks (malware, hacks, phishing, social engineering…).
Compliance
Multi-factor authentication helps organisations comply with legal requirements and data-protection standards like the GDPR. Healthcare, finance, and governmental entities require companies to follow strict guidelines that protect consumer rights and minimise risk. The security requirements also need to be able to adapt to the specific needs of every company.
A customisable solution
Each authentication factor offers several options, therefore allowing companies to personalise their user experience in line with their needs. One example of this is smartphones with fingerprint scanners to boost users digital security.
Ease of seamless login
Multi-factor authentication grants users access to their database thanks to single sign on (SSO), a login method consisting of a one time password (OTP) generally consisting of letters, numbers, or special characters sent to the user for a single login.
How does multi-factor authentication work?
One of the most common MFA methods users come across is one time passwords. OTPs are codes consisting of 4 to 8 digits mostly sent via e-mail, SMS, or dedicated mobile applications.
The use of multiple identification factors is an additional defence against cyberattacks. In other words, even if a cybercriminal manages to get hold of your username and password, they will need to have the second authentication factor to access your account or information.
The actual factors used in MFA can vary but generally fall into three categories:
- Knowledge (password or PIN code)
- Possession (badge or smartphone)
- Inherence (biometric fingerprints, voice recognition)
Multi-factor authentication is generally activated in the user account settings, and once enabled, identity has to be verified in two ways before account access is gained.
- Firstly, by entering a password.
- Secondly, by an authentication code usually communicated via e-mail, SMS, phone, or a dedicated confirmation code app installed on the user’s device. This code is confidential and generally only valid for a few minutes.
- Thirdly and finally (optional), multi-factor authentication can also be set up to encompass extra factors such as location, where the system checks user IP address or GPS location or additional factors that analyse user models and context for additional confirmation.
Multi-factor authentication has become an essential element in protecting our data in an ever-more connected world. It allows the risk of hacking and personal and professional data theft to be drastically reduced. Implementing a multi-factor authentication solution ensures efficient and consistent data security.
