# Set up Security
The first step is to assign security roles to users.
TextSMS4Dynamics has the following security roles:
{% tabs %}
{% tab title="TextSMS4Dynamics Administrator" %}
The user with **TextSMS4Dynamics** **Administrator** security role is in charge of setting up of the solution. They can setup the Twilio Account and integrate it with Dynamics 365 CRM, Create Configurations, Record Types, Customize Templates, etc.
{% endtab %}
{% tab title="TextSMS4Dynamics User " %}
The user with **TextSMS4Dynamics User** security role can only message with the customer and convert them into lead, opportunity, etc.
{% endtab %}
{% endtabs %}
