As technology advances, so do the methods cybercriminals use to exploit it. To protect ourselves and our sensitive data, we’ve adopted various security measures, one of which is Multi-Factor Authentication (MFA). In this blog post, we’ll explore MFA fatigue, its consequences, and how to overcome it with best practices and examples from companies that have managed it well.
What is Multi-Factor Authentication (MFA)?
MFA is a security process that requires users to provide multiple forms of identification to verify their identity before accessing an account or service. Typically, this involves at least two factors from any of these categories:
- Something you know (e.g., password, PIN)
- Something you have (e.g., physical token, smartphone)
- Something you are (e.g., fingerprint, facial recognition)
MFA provides an added layer of security, making it more challenging for attackers to gain unauthorized access to your accounts.
The Issue: MFA Fatigue
As effective as MFA is, constantly inputting multiple forms of authentication can become tiresome for users. This phenomenon, known as “MFA fatigue,” can lead to negative consequences such as:
- Users disabling MFA on their accounts
- Reusing weak or easily guessed passwords
- Ignoring security alerts and notifications
- Clicking authorizations not actually prompted by the user
These actions put users at higher risk of data breaches and cyberattacks.
Solutions and Best Practices to Overcome MFA Fatigue
To address MFA fatigue, companies must strike a balance between strong security measures and user-friendly experiences. Here are some best practices to consider:
Streamline the authentication process
Use adaptive authentication, which adjusts the level of required authentication based on factors like user behavior, location, and device. This way, users only need to complete additional authentication steps when necessary.
Choose the right MFA method
Offer users a variety of authentication methods, such as biometrics, mobile push notifications, or one-time passwords (OTPs) via text messages or authenticator apps. By giving users options, they can choose the most convenient method for them.
Educate users on the importance of MFA
Regularly inform users about the benefits of MFA and the risks of disabling it. Share statistics and real-life examples of how MFA has prevented cyberattacks.
Companies that handled MFA fatigue well
Microsoft is an excellent example of a company that has tackled MFA fatigue by offering various authentication methods, such as Windows Hello (biometric authentication), Microsoft Authenticator app, and OTPs via text messages or phone calls.
Recently, Microsoft has implemented a new feature in its MFA process: number matching prompts. Basically, when logging in for the first time or when there is a high risk of fraud, Microsoft will display a number on the user’s login screen which they must enter into their MFA app. Once the user opens and accepts the prompt to approve the request, they will be presented with another number which they need to type into the login page in order for authentication to be successful.
This small but significant change enables users to have more variety in their MFA prompts and lessens the effects of fatigue caused by repeatedly having to use the same method over and over again. If someone is trying to access an unauthorized account, exploitation of MFA fatigue is much more difficult. Additionally, it makes it harder for hackers who are trying to guess your credentials since each prompt is different every time you log in.
Actionable Tips to Avoid MFA Fatigue
- Use a password manager to store and autofill your login credentials securely.
- Enable MFA on all accounts where it’s available, prioritizing sensitive accounts like banking and email.
- Keep your devices updated with the latest security patches and antivirus software.
Overall, regularly updating security measures such as Multi-Factor Authentication (MFA) is essential in protecting users against cyber threats. The recent update from Microsoft requiring a number prompt adds an extra layer of security while also making it easier for users by providing them with more options when authenticating their identity.
