Almost every online step of a Spanish immigration procedure — filing a renewal, checking your file, paying a fee, downloading a certificate — asks you to prove who you are electronically. There are two tools most foreign residents end up needing: Cl@ve and the FNMT digital certificate.
Neither of them is required to book an appointment. They matter for everything that happens before and after it.
A state identification system. You register once, and from then on you log in with your NIE plus a code (Cl@ve PIN, sent for single use, or Cl@ve Permanente with a password). Easiest to obtain, enough for most consultations.
Issued by the FNMT. It is a file — or a card — that signs on your behalf. It is what electronic filings and legal representation generally require, and it works without a phone signal.
Only for Spanish nationals. Foreign residents cannot use this route: the TIE has no signing chip.
You can still do everything in person, and a lawyer or authorised representative can act for you with their own certificate. But without one of the two you will depend on appointments for things that could be done from home in five minutes — including checking whether your card has been resolved.

General information only; this is not legal advice. Requirements and timeframes can change.
No. The system identifies you by DNI or NIE, so you need your number assigned and a valid document first.
Cl@ve if you mainly want to check things and pay fees; it is quicker to obtain. The digital certificate if you plan to file applications electronically or act for a family member, because more procedures accept it.
Yes. Both Cl@ve and the FNMT certificate for individuals are free. Any site charging you for them is not the official source.
Yes, it is issued for a limited period and must be renewed before the expiry date. If you let it lapse, you have to verify your identity in person again.
You do not lose the registration, but the codes go to the number on file. If you change your number, update it in the system or you will not receive the PIN.
No. The appointment does not require electronic identification. What you do need at the appointment is the correct form, the paid fee receipt and your documents.
We monitor the official system continuously, and you only pay once the appointment is confirmed.
