In order to access your mailchimp account to set up email list subscribe forms on your website, we will need to have two-factor authentication, aka: 2FA, turned off on your Mailchimp account.
Here’s how to do it.
Once you log into your account, click on your name in the top right hand corner of the screen and then click on “Account”
Then locate “Settings” and then “Security”
This will bring you to your “Account security” page. From this page, you will be able to disable two factor authentication. If the buttons say “Enable” it means that it is turned off.
