# Setting Up and Using Multi-Factor Authentication (MFA)

> **Applies to:** Microsoft 365 accounts managed under Guardian or Titan Tiers
> **Secured via:** Azure AD Premium (P1), Microsoft Authenticator, Conditional Access

## Why MFA Matters

Multi-Factor Authentication (MFA) adds a powerful layer of protection to your Microsoft 365 account by requiring a second step—beyond your password—to verify your identity. With Office Heroes, MFA is **required by policy** to meet compliance and security standards such as HIPAA, GLBA, NIST, and FTC Safeguards.

## Step 1: Enroll in MFA

> Enforced via Office Heroes' identity protection tools in Azure AD.

### Go to the MFA Setup Portal:

### Steps to Enroll:

1. **Sign in** with your Office Heroes-managed Microsoft 365 email and password.
2. **Follow the prompt to register** for MFA.
3. **Choose your authentication method**:
   - **Microsoft Authenticator App** (Recommended)
   - **Phone call**
   - **Text message**
4. **Verify the method** by entering the code or approving the notification.

Once enrolled, this will become your default second step during login.

## Step 2: Signing In with MFA

When logging into Microsoft 365 apps or services:

1. **Enter your email and password.**
2. **Approve the MFA request**, which may come in the form of:
   - A **push notification** to your Authenticator app
   - A **6-digit verification code**
   - A **phone call** (automated)

> For security, Office Heroes logs and analyzes all MFA sign-ins.

## Managing Your MFA Methods

> Use this when you get a new phone or need to change how you authenticate.

### Manage MFA Settings:

### Recommended Setup:

- Set up **two** methods (e.g., Authenticator App + Phone Number)
- Add a **backup method** in case of device loss

## Troubleshooting MFA Issues

| Problem | Solution |
| --- | --- |
| **New phone, old MFA app doesn’t work** | Visit the Security Info page and add your new device. You may need an admin reset. |
| **Not receiving code/text** | Check your signal, ensure the number is correct, and try an alternate method. |
| **App notifications not showing up** | Make sure notifications are enabled for Microsoft Authenticator. |
| **Locked out completely** | Contact your Office Heroes admin or help desk to reset MFA methods. |
