Sign with FranceConnect

If you already have an account on impots.gouv.fr (the French tax portal) or on ameli (French national health insurance), you have FranceConnect — whatever your nationality. It lets you sign a document with an advanced signature, with a verified identity, with no prior formalities and at the best price for this level.

What you need

An account with any FranceConnect identity provider: impots.gouv.fr, ameli, Identité Numérique La Poste, the MSA (the agricultural social security scheme), and others, which you will find on the FranceConnect website. There is nothing to create: you log in with the credentials you already use.

Some providers authenticate you directly in the browser; others send you to their mobile app. In that case, keep your phone within reach.

How the signing works

1. On 1-signature, you upload your document, place your signature and choose level 3.
2. When it is time to sign, you choose your identity provider on the FranceConnect page, and log in to it.
3. Your identity is passed on, and the signature is applied.
4. You download the signed document and its evidence file.

What FranceConnect gives you

Your identity is not declared, it is supplied by the administration: this is what makes this signature an advanced signature, linked to you in a verifiable way. It is the level that suits most contractual commitments — an employment contract, a lease, a formality that requires an advanced signature.

If the identity does not match

Your name is supplied by FranceConnect. If it does not match the name you declared on 1-signature, the signing stops without using your stars. This is a safeguard: a typo in your name cannot produce a false signature.

Without a FranceConnect account

Level 4 also produces an advanced signature, with a certificate issued in your first and last names and a code received by SMS. But nobody verifies your identity there: the certificate bears the name you typed, exactly as typed. Read it over carefully.
