# Organisation settings - Invitations

You can use the settings for `Invitations` to make adjustments that affect the process of inviting participants to your organisation.

To better protect the security of your organisation's data from unauthorised access, you have the option of obliging the participant to set up [two-factor authentication](https://docs.groupalarm.com/en/article/profile-settings-1daklkt/#3-set-up-two-factor-authentication) for their personal user account. It will then not be possible for the participant to join without setting this up.

You can also add your own text to the invitation email under `Custom invitation text`. This allows you to send the participant important information with the invitation, such as a note to install the GroupAlarm App.
