Don't know which version of MailerLite you're using? Click here to find out!

Two-factor authentication (2FA) is a two-step login process that requires your username and password, as well as a unique code that is provided by any authenticator app, such as Google Authenticator, Authy, and Duo Security. This additional second step helps ensure that it is really you who is logging in to your account.

To set up 2FA in your MailerLite account:

  1. On the top right corner of the page, click on the dropdown arrow next to your profile name, and select My profile.

2. Scroll down to the Two-factor authentication and click Enable.

3. Follow the instructions on the screen and link your authenticator app with your MailerLite account by scanning the QR barcode provided on your MailerLite profile page.

4. Enter the code that has been generated on the authenticator app and then click Set up.

As a precaution, we provide a set of 10 recovery codes that you can download and use as keys to sign in when you can’t access your device. Just click Download recovery codes to automatically download them. 

We highly suggest you save these codes in a Text file or even print them out and keep them in a safe place.

If you are the Admin of the account, you have the ability to enforce two-factor authentication for all users on your account. This means that all users within the account will be required to set up 2FA the next time they log in, and they won’t be able to disable it.

To do this:

  1. Navigate to Account settings.

2. Go to the Users tab.

3. Choose the Security tab.

4. Toggle the option ON to enforce two-factor authentication across all account users.

When this setting is enabled, all new users joining the account will also be prompted to set up 2FA during their profile setup.
