Enable Two-Factor Authentication (2FA)

Introduction

Two-Factor Authentication (2FA) adds an extra layer of security to your login process. In addition to your regular password, you'll need to enter a One-Time Password (OTP) that will be sent to your registered email address.

What Happens When 2FA is Enabled

  • The mandatory 30-day password reset will be lifted.

  • After entering your password, you’ll be prompted to enter a verification code, which will be sent to your registered email. This OTP code must be entered to complete the login process.

How Users Use 2FA via Email

Once the admin enables 2FA for your company, there’s no need for users to take any further action. 2FA will be automatically linked to the email address that was used during registration.

Here are the updated steps:

  • Login to the Account

    • Users log in using their username and password.

  • Prompt for 2FA Verification

    • After entering the password, users will be prompted to verify their identity through 2FA.

  • Enter the Verification Cod

    • A 6-digit OTP will be sent to the user’s registered email address. If it’s not found in the inbox, check the SPAM or Junk folder.

Optional: Mark "Remember the device for 10 days".

This setting applies to trusted devices. If you access the platform from a different browser or after clearing cookies, you will need to re-authenticate.

  • Access the Platform

    • After entering the correct OTP code, users will be granted access to the platform.
