Access the sede electrónica of your Comunidad Autónoma with Cl@ve (and signing)

What you need to have to hand

1. DNI or TIE in date and its número de soporte (on the back).
2. Mobile with data/SMS and the app Cl@ve PIN installed.
3. Email you actually read.
4. PC with AutoFirma if the trámite requires signing.
5. Camera and mic if you register for Cl@ve by videollamada.
6. Certificado FNMT/DNIe optional as a lifesaver for stubborn signatures.

Documentation

• DNI (or TIE with NIE) and the número de soporte.
• Mobile phone and email (they’re your channel with Cl@ve).
• Activation code if you get a carta invitación (only if you choose that registration).
• AutoFirma installed if you’re going to sign documents.

Step by step

1. Registro en Cl@ve: go to https://clave.gob.es and choose registro by videollamada, with certificado or with carta. Complete the registration and link your mobile.
2. Activate the app: install Cl@ve PIN, scan the QR when asked and check it generates PINs reliably.
3. Prepare signing: if the trámite asks for it, install AutoFirma from https://firmaelectronica.gob.es/Home/Descargas.html and run a signature test.
4. Enter your regional sede: useful examples: Madrid (https://sede.madrid.es), Andalucía (https://www.juntadeandalucia.es/sede), Catalunya (https://seu.gencat.cat), C. Valenciana (https://sede.gva.es), Galicia (https://sede.xunta.gal). Click “Acceder con Cl@ve”.
5. Identify yourself: pick Cl@ve PIN or Cl@ve Permanente, generate the PIN in the app and enter it fast (it expires).
6. Sign if needed: if the sede requires it, use Cl@ve Firma (they’ll send a one‑time key) or use certificado FNMT/DNIe if Cl@ve Firma isn’t accepted.
7. Receipt and tasas: download the resguardo and pay the tasa autonómica in the payment gateway if applicable. Keep the PDF like it’s gold.

Tricks that save you time

• Test the app before starting the trámite so you don’t lose the PIN out of nerves.
• If AutoFirma won’t start, restart the browser and disable extensions (ad‑blockers, overprotective AV).
• Avoid Monday 09:00 and month‑end: virtual queues, errors and stress.
• Have a certificado FNMT or DNIe ready: some trámites won’t accept Cl@ve Firma and you don’t want to find out late.
• Use Chrome/Edge. Safari/Firefox sometimes mess up signing.

Typical mistakes that can ruin the trámite

• Expired PIN: you request the PIN too early and when you need to sign it’s already invalid. Request it just before use.
• Incompatible browser: signatures that won’t launch because of the browser. Switch to Chrome/Edge and disable extensions.
• Insufficient registration level: a basic Cl@ve registration won’t work for some signatures. Upgrade to Cl@ve avanzada (video or office).
• Poorly scanned document: you upload a corrupt or unreadable PDF and they reject it. Check size and legibility first.
• Not saving the receipt: rookie mistake. Without the resguardo, filing a complaint is a pain. Download it and back it up to the cloud.
