# Set up two-factor authentication

> Two-factor authentication (2FA) is a security method that ensures a user is the only person who can access their Talon.One account.

> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

<FeatureAccessInfoBox/>

When two-factor authentication is enabled, users of your organization are required to enter
a **one-time security code** sent to their email address, in addition to their password,
when signing in to Talon.One.

This adds an extra layer of protection to their account and increases the overall security
of your organization.

## Enable two-factor authentication

To enable two-factor authentication for all users of your organization:

1. In the lower-left corner of the Campaign Manager, click <Account className="icon"/> **Account** > <Org className="icon"/> **Organization** > **2FA**.
1. Toggle the **Two-Factor Authentication** button.
1. Select when users are required to enter a one-time security code:

    - Each time they sign in to their Talon.One account on a **new device**, and every 30
      days after that.
    - Each time they sign in to their Talon.One account.

  :::note
    - Two-factor authentication is immediately enabled when you toggle the button.
    - Each frequency option is applied right after you select it.
    - You cannot enable two-factor authentication when [single sign-on](/docs/product/account/account-settings/set-up-sso.md)
      is enabled for your organization. Enabling single sign-on automatically disables
      two-factor authentication.
