Set Up 2-Factor Authentication with SMS

Set up 2-factor authentication to enhance your account's security. With 2-factor authentication enabled in Mailchimp, you need your login credentials and a one-time passcode to log in to your account. This passcode is sent via SMS or generated by an authenticator app.

In this article, you'll learn how to use 2-factor authentication with SMS.

Before you start

Here are some things to know before you begin this process.

• If you prefer, you can use an authenticator app on your mobile device for your 2-factor authentication.
• When an Owner or Admin enables 2-factor authentication for their login, all additional users with access to the account will also be required to set up 2-factor authentication the next time they log in. To learn more about user levels, check out Manage User Levels in Your Account.
• Learn what to do if you lose your mobile device.

Enable remember me options

By default, Mailchimp requires you to log in and complete 2-factor authentication every time you return to your account after leaving it.

To enable remember me options, follow these steps.

1. Click your profile icon and choose Cookie Preferences.
2. Use the toggle to enable Performance and Functionality Cookies.
3. Click Confirm My Choices.
4. Next time you log in, check the boxes next to Keep me logged in and Skip this for two weeks.

If you clear your browser cookies, you’ll need to repeat these steps to enable this functionality again. You’ll always be asked to log in and complete 2-factor authentication if you access Mailchimp on a different or unknown device.

Reconfigure 2-factor authentication

Once you’ve set up 2-factor authentication, you won’t be able to remove or disable it. If you need to update your phone number or switch your authentication method, you can reconfigure your 2-factor authentication settings.

From your Account security page, click Reconfigure and follow the prompts to update your authentication phone number. Or, click Switch to authenticator app to switch your authentication method, and follow the prompts to Set Up a 2-Factor Authentication App at Login.
