Cl@ve and the certificado digital: Spain's login layer, decoded

The official portal structures the family: Cl@ve PIN (a code with limited validity), Cl@ve Permanente (a durable password for regular users) and Cl@ve Móvil with its app. Registration — the step that gates everything — runs by four official routes: online with automatic video-identification; via an invitation letter; online with an electronic certificate or DNIe; or in person at a registration office. For a newcomer holding only an NIE and no Spanish digital credential yet, the video-ID and in-person routes are the two real doors.

The FNMT's certificado de persona física is the certificate most gestorías mean when they say "get your digital certificate": the sede lists the issue routes — certificate with video-identification (app-based), with in-person accreditation (request online, prove identity at an office, download), and with DNIe — each with its configuration, request, accreditation and download steps. It installs into your browser and signs anything the administration throws at you.

The honest map: Cl@ve PIN covers most one-off tasks (tax filings, appointment systems, checking a file); the certificado digital is worth the setup pain if you'll deal with Spanish administration monthly — empadronamiento certificates, TGSS filings, extranjería lookups. Both key on your NIE, which is why the NIE is step zero — and both are the Spanish ancestors of the EUDI wallet now rolling toward 2027.
