It is your electronic ID for carrying out legal procedures <a href="https://www.chusmeando.com/tag/online/”>online (such as signing documents or requesting Social Security reports). <a href="https://www.chusmeando.com/informatica-y-tecnologia/como-funcionaba-la-innovadora-imprenta-de-gutenberg/" title="How Gutenberg’s innovative printing press worked and why its invention continues to be considered one of the most influential in human history”>In 2025 it is still mandatory for:

• Companies and self-employed workers.
• Any procedure with the Tax Office, Town Halls, or the INEM.

📢 2025 Update: It is now integrated with the European Digital Identity Wallet (eIDAS 2.0).

📲 How to Get It in 2025? (3 Methods)

1. In Person (The Easiest)

1. Book an appointment on <a href="https://www.sede.fnmt.gob.es/certificados” target=”_blank” rel=”noreferrer noopener”>this FNMT website.

   • Physical DNI/NIE.
   • Application code (you generate it online beforehand).
3. They give you a USB with the certificate or you download it instantly via SMS.

⚡ New: Some regions now use self-service machines (like those at Renfe) to issue them in 5 minutes.

2. Online with Video Identification

1. Use the FNMT QR app.
2. Scan a code with your phone + take a selfie with head turns (like at banks).
3. Download the certificate within 24h.

⚠️ 2025 Requirements:

• Phone with NFC (to read the electronic DNI).
• Account in Cl@ve Firma.

3. With Electronic DNI (DNIe 5.0)

• DNIs issued since 2024 already come with the certificate pre-installed. You just need to:
  1. Insert it into a card reader.
  2. Use the PIN you were given when you got it.

🛠 How Is It Used?

1. In Chrome/Edge 2025:
   • Go to an official website (e.g., Tax Agency).
   • When it asks for identification, choose “Digital Certificate”.
   • Select your .pfx file or connect the electronic DNI.
2. On Mobile:
   • Official apps (such as AEAT) now automatically detect the certificate if you have it in the system store.

💡 Pro Tip: In Windows 11 24H2, there is a new option to sync it with your Microsoft account and use it on any device.

❌ Typical Errors and Solutions (2025)

🔍 Key data: 70% of failures in 2025 are due to not updating Java (no longer necessary) or using Windows 10 without patches.

🔄 Renewal in 2025

• Expires after 4 years (it used to be 2).
• Automatic renewal: If you use the FNMT QR app, it notifies you 1 month in advance.
• Cost: It is still free for individuals.

📅 New: You can renew it from abroad with an appointment at consulates (previously impossible).

🚀 What Is It Exactly For?

• Tax Office: File income tax, VAT, or forms such as the 720.
• Social Security: Request employment history or sick leave.
• Town Halls: Pay taxes such as property tax online.
• Banks: Sign digital mortgages (now 90% allow it).

Real example: With the certificate, you can open a business in 24h from www.puntonegocio.gob.es.

📢 Conclusion

The digital certificate is easier than ever in 2025, but it still causes problems if you don’t set it up properly. My recommendation? Use the in-person method and save it on an encrypted USB drive.
