Multi-Factor Authentication (MFA)
Enhance security by enabling and configuring multi-factor authentication for your Firebase users.
Secure Your App with MFA
Multi-Factor Authentication (MFA) adds an extra layer of security to user accounts. Instead of just a password, users need a second "factor" to prove their identity.
This significantly reduces the risk of unauthorized access, even if a password is stolen.
Firebase MFA Overview
Firebase Authentication provides built-in support for MFA. It allows users to enroll multiple second factors, like a phone number for SMS verification.
When MFA is enabled, users first sign in with their primary method (e.g., email/password), then complete a challenge with one of their enrolled second factors.
