How do I enable Two Factor Authentication (2FA) on user login?

This is done by:

> Go to Settings(top right corner)

> Users

> Click the 3 dots in the right side next to the user

> click the pencil(edit user)

> mark the field "Require two factor"

> press Confirm.

When the user logs in (s)he will be prompted to scan the displayed QR code and set up the login using an authenticator app. The user can then use the set-up application to receive a unique code to enter upon each login.
