Plain English: public-sector single sign-on
Definition
You must first register through one of the available in-person or online Cl@ve registration routes. A requested PIN is one-time and currently expires after ten minutes. Each public service exposes the methods allowed by its security level, so being able to identify yourself with Cl@ve PIN does not guarantee that the same method can sign or finish every filing.
- Choose the official Cl@ve registration route that fits the available identity evidence and access method.
- Treat the PIN as a one-time credential with the current ten-minute validity window.
- Check the exact service's security level and accepted identification or signature methods before the deadline.
Example: a working Cl@ve PIN can still be insufficient when the final filing requires a digital certificate or another stronger method.
Where this appears
Cl@ve PIN can appear in Spanish forms, appointment screens, official letters, PDF instructions, receipts, or portal status messages. This term usually appears in identity, certificate, or digital-access workflows. Check whether the task needs a passport, NIE, TIE, certificado digital, Cl@ve, AutoFirma, or another official credential.
Use the term as a clue, not the whole answer. A public definition can explain the usual meaning, but a personal document may change the deadline, office route, evidence required, or risk of ignoring the message.
