Creating a data.shom.fr account allows you to save your drawings so that you can open them later.
The account is free and shared with the Shom shop: a single account is all you need to connect on both sites.
From any data.shom.fr page, click on the silhouette icon.
Click on "Create an account".
Fill the mandatory fields and click on "Créer un compte".
A confirmation e-mail will be sent to the e-mail address you entered. Click on the email confirmation link.
This takes you to the shop, where you are logged in. You will receive an email informing you that your registration has been successful.
With the same identifiers (email address and password) you can connect to data.shom.fr.
