What is a digital certificate, and what is it used for?
A digital certificate is an electronic credential that allows you to identify yourself and sign securely online. With it, you can complete administrative procedures online without having to go anywhere: file taxes, view records, access notifications, apply for financial aid, and sign applications and official documents.
The FNMT explains the available methods for obtaining an individual certificate (including video identification, in-person verification, an electronic ID card, or a mobile device).
Common examples of usage (bulleted list):
Submitting Documents and Requests Online
Access to Online Portals
Signing Documents with AutoFirma
Management of Recurring Administrative Procedures (Self-Employed Individuals/Companies)
Types of Digital Certificates We Process
Certificate of Natural Person (Citizen)
Ideal for personal administrative procedures: AEAT, Social Security, SEPE, city halls, scholarships, financial aid, etc. (The FNMT offers it through various methods of acquisition.)
Certificates for Companies and Representatives
If you need to act on behalf of a company, the FNMT offers certificates of representation (e.g., representative of a legal entity and other cases).
Certificates for Companies and Representatives
In Catalonia, there is the idCAT Certificate, which can be obtained online via video identification (with a valid DNI or TIE) or in person at registration offices.
How We Do It With You (3-Step Process)
Step 1 — We verify your case and the type of certificate
We’ll confirm which one you need (individual, representative, solution in Catalonia, etc.) and what requirements apply.
Step 2 — Processing and Identity Verification
Depending on the type, it may require video verification or in-person verification, depending on the provider and method (FNMT and AOC offer these options).
Step 3 — Installation, Testing, and Backup
We’ll help you get it up and running on your computer and sign documents correctly. AutoFirma uses certificates installed in the system or browser store, and its official manual provides installation instructions.
Digital Certificate Renewal and Recovery
If your certificate is about to expire, we’ll help you renew it and avoid common mistakes (such as trying to renew it from a browser or computer where it isn’t installed). The FNMT states that to renew your certificate, you must authenticate yourself using the certificate installed in the browser from which you’re performing the renewal.

Frequently Asked Questions About Obtaining Digital Certificates
How long does it take to get a digital certificate?
It depends on the type and method of verification (video verification or in-person). In general, the actual time varies depending on the method and the provider’s identity verification. We’ll recommend the fastest and most appropriate option for your situation.
Can I get a digital certificate via video call or video identification?
Yes, some systems offer the option to obtain the certificate via video identification. The FNMT allows for “video identification” for individual certificates, and idCAT also offers online application with a valid DNI or TIE.
What is the difference between FNMT and idCAT Certificat?
Both allow you to verify your identity and sign digitally, but the idCAT is linked to the Generalitat’s ecosystem and is obtained through the registration channels and entities specified by AOC. We’ll guide you based on the type of procedure you need to complete.
Can I use my digital certificate for the IRS and Social Security?
For many procedures, yes. The government provides certificate-based identification systems that allow you to interact electronically with public agencies.
Do I need to install AutoFirma?
AutoFirma is often used to sign certain documents. The official manual explains the installation process and system requirements, and we’ll help you get it up and running.
Can I install the certificate on more than one computer?
It depends on the type of certificate and how it is exported or imported. That’s why it’s important to back it up properly and configure each computer securely. We’ll walk you through it step by step.
What happens if I switch computers or browsers?
This is one of the most common issues. If the certificate hasn’t been exported, you could “lose” it. We’ll help you install it on your new computer and keep a secure copy for future migrations.
How do you renew a digital certificate?
For FNMT certificates, renewal typically requires that the certificate to be renewed be installed in the browser from which the renewal is requested. We’ll check the status for you and guide you through the process.
Can I get a certificate to act on behalf of my company?
Yes. There are representative certificates (for example, for legal entities) that require a specific application and accreditation process. We’ll help you determine which one applies to your situation and guide you through the process.
How do I know that the certificate issuer is trustworthy?
In Spain, there is a Trusted List (TSL) published by the government that includes qualified, supervised providers. We work with valid solutions and will explain which one applies to your situation.
