Multi-Factor Authentication (MFA)

What is MFA?

Multi-Factor Authentication (MFA) adds an extra layer of security to your account. In addition to your password, you’ll be asked to verify your identity using a second factor (a code sent to your mobile device or generated by an app). 

Why MFA matters

  • 🔐 Improved security: Even if your password is compromised, MFA keeps your account safe. 

  • 🧠 Peace of mind: Prevents unauthorized access and reduces the risk of fraud. 

  • ✅ Best practice: Trusted by leading organizations and security experts worldwide. 

What you'll need

Before you begin, you will need to have: 

  1. A smartphone

  2. Access to the App Store (iPhone) or Google Play Store (Android) 

  3. Your Ratio.City account login information (username and password)

  4. A computer or device where you can log in to your account 

Step-by-step: Setting up MFA with a QR code

Step 1: Download an authenticator app (if you don’t already have one) 

You’ll need a special app to get your login code. We recommend: 

  • Microsoft Authenticator 

  • Google Authenticator 

To install the app:

  • Go to the App Store or Google Play Store on your phone

  • Search for Microsoft Authenticator or Google Authenticator 

  • Tap ‘Install’

Step 2: Log in to your Ratio.City account on your computer 

  • Go to your login page

  • Enter your username and password as usual

  • You’ll be prompted to set up MFA by ‘scan this QR code with Google Authenticator (or similar) app’

 

Step 3: Open the authenticator app you downloaded on your phone

  • Open the app you just installed

  • Tap the ‘+’ button in Google Authenticator or blue QR code icon in Microsoft Authenticator

  • Use your phone’s camera to scan the QR code shown on your computer screen

| 💡Tip: Hold your phone steady and point the camera at the QR code, it will automatically recognize it!

 

Step 4: 🎉 You’re set up!

  • The app will start showing 6-digit codes that change every 30 seconds (see below for further details on how to login with your one-time password).

  • These codes are your extra layer of security

  • Done! MFA is now active on your account

Step-by-step: Logging in to Ratio.City with MFA using a one-time password

Step 1: Open your authenticator app

  • Locate and open the authenticator app on your mobile device

  • If prompted, unlock your phone or app with a PIN, fingerprint, or face scan

Step 2: Find the code for your account

  • Look for your work or application account name in the app

  • You will see a 6-digit code (or 8-digit in some cases) next to it

  • The countdown timer or moving bar shows how long the code is valid

Step 3: Enter the one-time password prompted on the screen

  • On your login page, type the code exactly as shown in your authenticator app

  • Do not include spaces

  • Press Submit or Verify before the timer runs out

 

Step 4: If the code expires

  • If the timer runs out before you submit, wait for the next code to appear

  • Enter the new code and click Submit

Note: There is an option to select “remember this device for 30 days” when submitting your code, otherwise MFA is required every 3 days.
