You cannot activate two-factor login in your organization settings, as this is an extra module. You must therefore contact FirstAgenda Support at firstname.lastname@example.org, for help with activating two-factor login.
With two-factor login, you can increase safety in the use of FirstAgenda further. There are two ways you can use two-factor login.
One is that you can choose that the users of your organization must log in with both their password and a received SMS code every time they log on FirstAgenda.
The second way is that they only have to log on with their password and the received SMS code when they log into FirstAgenda outside your organization's network. You have the option to select multiple network that users can access without having to write both password and SMS code.
