# Enforce MFA

> Require multi-factor authentication for everyone in your organization or just yourself.

Enabling org-wide MFA makes multi-factor authentication mandatory for every user in your organization. When enabled, if you haven't enrolled, you're prompted to set up an authenticator app on your next login.

## Enforce MFA for all users

1. In ION, go to **Settings > Organization > Authentication**.
2. In the **Multi-Factor Authentication** card, turn on **Require MFA for all users**.

<Warning>
  Org-wide MFA applies to everyone the moment you turn it on. To avoid locking
  users out, confirm your team can enroll an authenticator app, and validate the
  change in a sandbox tenant first if you have one.
</Warning>

## Enforce MFA for yourself

You can enable MFA on your own profile without org-wide enforcement enabled. After enabling, log out and sign back in to start the MFA setup flow. If you lose access to your MFA device, see [Troubleshooting sign-in issues](/administration/authentication-settings/sign-in#troubleshooting).
