Log in via **Google**, **Office 365** or with your [**connection key.**](https://support.signitic.com/fr/articles/8224225-copier-la-cle-de-connexion-d-un-utilisateur.md)

## **❹** Create a signature

> **Warning:** **WARNING: This may result in the deletion of your current signatures. Signitic will replace all signatures that contain your email.**

Open Apple Mail and go to the menu: _Mail > Settings > Signatures_ and create a signature by placing in the content of the signature [_votre.email@monentreprise.fr_](mailto:votre.email@monentreprise.fr) as shown in the screenshot below. The objective here is therefore to enter only your email address in the field; this will allow a connection to be created with the Signitic Agent.

Also remember to correctly respect the capital letters present in your email address for your connection to the agent to be properly taken into account. **(Example: If, when you log in, the agent displays your email address like this:** [**_Votre.EMAIL@monentreprise.fr_**](mailto:votre.email@monentreprise.fr) **_then you must copy exactly the same email address into the Apple Mail signature block.)_**

## **❺** Update your signature

Back in the Signitic client, update your signature by clicking on the "**Update**" button at the bottom of your profile page.
