Why should we use 2FA authentication?

Why should we use 2FA authentication?

Companies should use two-factor authentication (2FA) and, in particular, 2FA from DUO Security for several reasons

Find out below why companies should use two-factor authentication (2FA) and, in particular, 2FA from DUO Security.

Benefits of using 2FA

1. Enhanced security: - 2FA adds a second layer of protection on top of the usual password, making it much harder for attackers to access protected accounts, even if they have managed to find out the password. 2. Preventing unauthorised access: - Even if an attacker obtains a user’s password, they will not be able to access the account without the second authentication factor (for example, a code sent to their phone). 3. Reducing phishing risk: - 2FA makes phishing attacks less effective, since simply obtaining the password is not enough to compromise an account.

Step 2: Enrolling the device in Duo

  • Receiving the activation invitation: You will receive an e-mail or message with an activation link or QR code from your organisation’s system administrator.
  • Scanning the QR code: Open the Duo Mobile app and select the option to add a new account.
  • Scan the QR code you received.

Step 3: Using authentication with Duo Security

  • Connecting to the service: Access the service or application that uses Duo for authentication (for example, an e-mail portal, VPN, etc.).
  • Entering your credentials: Enter your username and password for your account, as usual.
  • The Duo prompt: After entering your credentials, you will be redirected to the Duo authentication screen.
  • You have several options for completing authentication:Push Notification: The Duo Mobile app will send a push notification to your phone. Approve the request to complete authentication.
  • Verification codes: The Duo Mobile app can generate a temporary code for you to enter in the authentication interface.
  • Phone call: Duo can make a phone call to your registered number, where you will confirm authentication.
  • Text message (SMS): You can receive a verification code via SMS.

Step 4: Confirming authentication

  • Approve/enter code: Depending on the method chosen, either approve the push notification or enter the generated or received code.
  • Access to the service: Once you confirm authentication, you will have access to the desired service or application.

Additional settings

  • Adding more devices: You can enrol several devices (for example, phone and tablet) for redundancy.
  • Account recovery: If your device is lost, you will need to contact the system administrator to reset your 2FA authentication. DUO Security also provides detailed documentation and video tutorials for setting up and using the service, which can be very useful for users and administrators alike.
