# Stop Building MFA from Scratch (And What to Do Instead)

As a Customer Advocate, I talk to founders, CTOs, and developers every single day. And there is one thing I hear constantly: everybody needs multi-factor authentication (MFA) right now. Whether it is to land an enterprise deal, pass a [SOC 2](https://auth0.com/docs/secure/data-privacy-and-compliance) audit, or just keep your users safe, it is become completely non-negotiable.

But here is the thing I have learned from listening to so many engineering teams: knowing you need MFA and actually building it are two very different beasts.

## What Is the Headache of Building MFA Yourself?

When teams decide to build MFA in-house, they often tell me it ended up being a much bigger project than they expected. It is never just a simple feature you add in an afternoon.

Your team suddenly has to figure out how to integrate authenticator apps, generate QR codes, handle backup recovery codes securely, and manage all the weird edge cases: like what happens when a user loses their phone.

Every week your developers spend [building and maintaining that login plumbing](https://auth0.com/blog/preventing-destructive-actions-with-step-up-authentication/) is a week they are not spending on your core product.

## Why Auth0 Is the Easier Way

This is exactly why Auth0 is built to take that heavy lifting off your team's plate. Implementation should not take weeks. 

Instead of building all that [complicated logic from scratch](https://auth0.com/blog/you-are-using-auth0-the-hard-way/), you can just flip a switch in your dashboard. You can even set it up so it only asks for [MFA when it really matters](https://auth0.com/docs/customize/actions/actions-overview), like if someone is logging in from a strange location or an unrecognized network. You get total control over the user experience, but we handle the messy stuff in the background.

## Which MFA Plan Is the Right Fit

We do not think security should be an afterthought. We have baked MFA directly into our paid plans so you can choose the exact setup you need and skip the tedious development phase.

| Feature | What Is Included |
| ----- | ----- |
| [**Pro MFA**](https://auth0.com/docs/secure/multi-factor-authentication) | This covers the standard authenticator apps (like Google Authenticator or Duo). It is included right out of the box in our B2C and B2B Essentials plans. |
| [**Enterprise MFA**](https://auth0.com/docs/secure/multi-factor-authentication) | When you need to support WebAuthn, Push Notifications to an app, SMS, or Voice. This is available as an add-on to B2B Essentials, and included fully in our Professional tiers. |

## Turn on MFA and Get Back to Building Customer Value

Your engineering team's time is simply too valuable to spend building login infrastructure from scratch. By [upgrading to a plan that includes MFA](https://auth0.com/blog/whatever-you-are-building-auth0-has-a-plan/), you get to check the compliance boxes, unblock those big enterprise deals, and let your developers get back to building the features your customers actually care about.

Ready to see how easy it is to turn on? Have your team check out our [MFA implementation docs.](https://auth0.com/docs/secure/multi-factor-authentication/enable-mfa)
