Grounding for the moment a démarche says "go to the official site". The job is to get the person to the correct official page and give the next concrete step — not to write a manual. The person authenticates and submits in their own session, always.

Prefer the démarche's own pinned URL

When the guide you are following names an exact page, use it — it is the authoritative target. The table below is for recognition (is this the real site?) and for when no exact page is pinned. Never invent a host that isn't official.

Official portals by domain (hosts verified 2026)

Démarche	Official host	Notes
Impôts (revenus, IFI, avis)	`impots.gouv.fr` → espace particulier at `cfspart.impots.gouv.fr`	"Votre espace particulier" → "Déclarer mes revenus".
Famille, logement (APL)	`caf.fr`	"Mon Compte" → "Mes démarches". CAF = Caisse d'allocations familiales.
Assurance maladie (carte Vitale)	`ameli.fr`	"Mon compte ameli".
Titre de séjour (étrangers)	`administration-etrangers-en-france.interieur.gouv.fr` (ANEF)	Demandes, renouvellements, validation VLS-TS.
Passeport, CNI	`france-titres.ants.gouv.fr` / `passeport.ants.gouv.fr` (ANTS)	Pré-demande en ligne ; dépôt en mairie équipée.
Carte grise (immatriculation)	`immatriculation.ants.gouv.fr` (ANTS)	100 % en ligne ; plus de guichet préfecture.
Emploi / chômage	`francetravail.fr`	Ex-Pôle emploi. Inscription = demande d'allocation.
Retraite	`lassuranceretraite.fr` ; vue tous régimes : `info-retraite.fr`	Demande unique inter-régimes (base + Agirc-Arrco).
Création d'entreprise / auto-entrepreneur	`formalites.entreprises.gouv.fr` (guichet unique INPI)	Création ; les déclarations de CA se font sur `autoentrepreneur.urssaf.fr`.
Urbanisme (permis, DP)	`service-public.gouv.fr` (AD'AU) ou le guichet (GNAU) de la commune	Beaucoup de communes ont leur propre guichet numérique.
Changement d'adresse, infos, annuaire, état civil	`service-public.gouv.fr`	"Je change de coordonnées" déclare l'adresse à plusieurs organismes d'un coup.

service-public.fr now redirects to service-public.gouv.fr — use the .gouv.fr host. When the démarche isn't in this table, route via service-public.gouv.fr (the official entry point) rather than guessing a host.

Recognising the real site — avoid paid look-alikes

French administrative services are free, but a whole industry of intermediary sites mimics them and charges fees (carte grise, passeport, acte de naissance, casier judiciaire, EHIC…). Protect the person:

Official sites end in .gouv.fr (or the historic operators caf.fr, ameli.fr, ants.gouv.fr, urssaf.fr, francetravail.fr, lassuranceretraite.fr).
A site that asks to be paid for a normally-free démarche, or a .com/.fr aggregator promising to "do it for you", is not the official service — steer the person back to the official host.
If the person shares a non-official URL for a free service, say so plainly and give the official one.

FranceConnect (login)

FranceConnect is the State's single sign-on: the person logs into a gov site by choosing an identity provider they already have. Current providers (2026): Impots (DGFiP), Compte Ameli, L'Identité Numérique La Poste, MSA, France Identité. (YRIS is being withdrawn.) For sensitive démarches a site may require FranceConnect+ (higher assurance), which accepts only L'Identité Numérique La Poste and France Identité.

The person always authenticates themselves. An agent has no credentials, never asks for a password, and cannot log in for them. If a page needs login, tell them to sign in (via FranceConnect if offered) and continue once they're in.
After FranceConnect they land back on the target site's logged-in space — point them at the right section there (e.g. "Déclarer mes revenus").

Agents with computer-use / browser control

If your agent can operate a browser (computer-use, browser automation), these rules still hold — they are what keeps assistance safe and legitimate:

Navigate and pre-fill only with the person's consent, on the official host, with the person watching.
Never handle secrets — not just passwords: IBAN / BIC / RIB, card numbers, one-time codes, full government-ID numbers. The person types those directly into the official portal; point at the field, never collect the value.
The person reviews every pre-filled value and performs the final submit themselves. Never claim a form was submitted for them, and never trigger the submit action autonomously.

Helping a person through a multi-step portal

Most portals are multi-page wizards (étapes). Keep guidance to the next step:

Name the exact entry point once on the site (menu item / button), e.g. impôts → "Déclarer mes revenus"; ANEF → "Demander ou renouveler un titre".
These flows paginate with "Étape suivante" / "Continuer" / "Valider" at the bottom; "Précédent" goes back; progress is usually saved automatically, so the person can stop and resume.
Cookie-consent banners appear first on most sites — mention them only if they're blocking.
Confirm the person is on the right page before walking through fields (URL on an official host above, page title matches the démarche).
One destination + one next action at a time. Don't dump the whole journey.
