Multi-Factor Authentication (MFA) – Setup & Security Guide

Setup & Security Guide

Multi-Factor Authentication (MFA) adds an extra layer of protection to your account. Instead of just entering your password, you’ll also confirm your identity using a second method — through an authentication app.

Why MFA Keeps You Safe

• Passwords can be stolen — through phishing emails, malware, or weak/reused passwords.
• MFA stops attackers even if they have your password — because they still need the extra code from your phone or app.
• It protects sensitive data — especially if you handle personal information or business-critical files.
• It reduces account takeovers — Microsoft reports MFA can block over 99% of automated attacks.

Think of MFA as adding an extra locked door — even if someone manages to unlock the first door, the second one keeps them from gaining access

Step-by-Step: How to Set Up MFA

1. Sign in to your account

• Go to the KEYinfinity login page.
• Enter your email and password as usual.
• If you prefer not to log out, consider selecting the 30-day 'Keep me signed in' option to avoid repeated use of MFA.

2. Start MFA setup

• You’ll be prompted to set up MFA after signing in.
• Click Sign in when asked to add additional security.

3. Setup your authentication app

• Authentication App (Recommended)
  • Download Microsoft Authenticator or Google Authenticator on your smartphone if you do not have this already.
  • Scan the QR code on the screen.

• Click Continue
• Enter the 6-digit code from the App  >  Click Verify.

5. Finish and test

• Sign out by clicking Logout on the next screen and sign back in to make sure your MFA is working.
• You should be prompted for your extra code after entering your password.

Tips for Using MFA

• Keep your phone secure — use a PIN, fingerprint, or face unlock.

• Don’t approve sign-in requests you didn’t make — it could be someone trying to break in.
