2FA with free version

Hi, I need some information.
With the update of iThemes Security to version 8.0 I noticed that now you can set two-factor authentication even if you don’t have the Pro version. I was surprised because I thought that this setting was only available for those who have the Pro version.
Can you confirm that I can safely install two-factor authentication on the Free version of your plugin?

Thank you in advance for the clarification and I apologize for the banality of the question.
