What is Multi-Factor Authentication (MFA) in Salesforce?
Multi-Factor Authentication (MFA) is a critical security feature in Salesforce that adds an extra layer of protection beyond just a username and password. It helps prevent unauthorized access, reduces security risks, and ensures compliance with industry regulations. In this guide, we’ll explore how MFA works in Salesforce, why it’s important, and how to set it up effectively.

What is Multi-Factor Authentication (MFA)?
MFA is a security mechanism that requires users to provide two or more authentication factors before gaining access to Salesforce. This ensures that even if a hacker steals a password, they cannot log in without the second verification step.
Example of MFA Authentication in Salesforce
1. User enters their Salesforce username and password (something they know).
2. Salesforce prompts for additional verification via a trusted device (something they have).
3. User approves the login request using an authentication app, security key, or biometric authentication.

Why is MFA Important in Salesforce?
1. Enhanced Security – Protects accounts from cyber threats like phishing and credential theft.
2. Regulatory Compliance – Meets security standards like GDPR, CCPA, and PCI DSS.
3. Prevents Unauthorized Access – Even if a password is compromised, attackers cannot log in.
How Does MFA Work in Salesforce?
Salesforce MFA requires users to authenticate using two different types of verification methods:
1. Primary Authentication: Username and password.
2. Secondary Authentication: A trusted verification method like an app or security key.
Supported MFA Methods in Salesforce
| MFA Method | Description | Example |
|---|---|---|
| Salesforce Authenticator App | Mobile app that provides one-tap push notifications. | User gets a login request on their phone and taps “Approve”. |
| Third-Party Authenticator Apps | Apps like Google Authenticator, Microsoft Authenticator, or Authy generate a one-time code. | User enters a 6-digit code from the app to log in. |
| Security Keys (Hardware-Based MFA) | Physical USB/NFC devices like YubiKey. | User inserts the key into their device to verify login. |
| Built-in Biometric Authentication | Uses device-based authentication like Face ID or fingerprint scan. | User verifies login with a fingerprint. |

How to Enable MFA in Salesforce (Step-by-Step Guide)
Step 1: Enable MFA in Salesforce Setup
1. Login to Salesforce and go to Setup.
2. Search for “Identity Verification” in the Quick Find box.
3. Under “Session Security Levels”, ensure that Multi-Factor Authentication is required for logins.
Step 2: Assign MFA to Users
1. Navigate to Setup → Users → Profiles.
2. Select the profile that requires MFA and click Edit.
3. Under “Login Security Level”, set MFA as Required.
Step 3: User Enrollment in MFA
1. The next time users log in, Salesforce prompts them to set up an authentication method.
2. Users can scan a QR code using Salesforce Authenticator or a third-party app.
3. Once linked, the app generates a verification code for future logins.
Example Code: Enforcing MFA in Salesforce Apex Code
To enforce MFA in Apex, you can use the UserLoginEvent trigger. Here’s an example:
trigger EnforceMFA on UserLogin (before insert) {
for (UserLogin login : Trigger.new) {
if (!login.isMfaAuthenticated) {
login.addError('Multi-Factor Authentication is required for this account.');
}
}
}Code Explanation:
This Apex trigger runs before a user logs in and checks if MFA authentication was used. The loop iterates through all login attempts and verifies if MFA is enabled. If MFA is not authenticated, the login request is blocked, and an error message is displayed. This ensures that only users with MFA enabled can access Salesforce.
