Log in the system to access the application. Authenticate through one of the two supported options, which can be configured by the system administrators. "Enter with a local certificate" (certificate installed in a computer) or "Enter with cloud-based certificate" (installed remotely). Use valid "User" and "Password" credentials. In case the system administrators have enabled the Signatures Verification option, you can access to the Signatures Verification Application to enter a request code and check the status of a signature request.

The system can present different options subject to the configuration set by the administrators. When authenticating with a digital certificate, if the user is not registered in the system, the system can either deny access or allow the user to self-register, requiring validation or not by an administrator. The user accessing for the first time to Viafirma Inbox can also be directed to the registration form if the system administrators have configured the application to do so.

The Viafirma inbox interface consists of the following sections:

• Header
• Main menu
• Personal menu
• Calendar and tasks
• Footer

The first step is adding a signature, once added it can be modified or deleted. In case a customized signature code is not defined, a generic one will be generated when signing. For users associated with more than one entity, instead of showing the email field, a list with the entities associated to the user and the email address assigned to each entity are displayed. The user can select the default email address for notifications.

Access the form for writing a new request by clicking on the "Write" button at the left side of the panel.  There are two ways of writing: basic and advanced.

• Basic writing: its content is subject to the configuration of your application, but the following fields will always be displayed: addressees, subject, message, documents to sign, attached documents and sender notification level.
• Advanced writing: includes all available fields.

When accessing the writing for the first time, the basic type is shown. Further accesses show the last type of writing used. To switch from one type to another, click on "Change to advanced writing" or "Change to basic writing", at the top right of the page.

Guidelines for writing requests and dealing with them are available in other pages of this section.
