Cl@ve: How to Register and Log In on Your Phone
Cl@ve logs you into Spanish government sites with the app or a password. It cannot sign a Mercurio extranjería filing. Register with your TIE support number. Last checked 17 August 2026.
Last checked: 17 August 2026. Official name for the phone method is Cl@ve Móvil (formerly Cl@ve PIN).
Cl@ve is how you log into tax, social security, town hall, traffic and many ICP pages from a phone, without a certificate on that device.
It identifies you. It does not sign. Filing a TIE-related renewal on Mercurio (for the types it lists: sign, then submit) needs eIdentifier and the digital certificate. ICP is appointments and lote. Side-by-side: eIdentifier vs Cl@ve.
How you log in (official)
Cl@ve Móvil — QR: choose Cl@ve Móvil → the page shows a QR and a 3-digit code → scan with the Cl@ve app → match the 3 digits on the phone and the page → confirm in the app. The 3 digits are a check, not a password you type back into the website. Official steps
Without QR: continue without scanning → NIE + support number → confirm in the app. After about a minute you may get a 6-digit SMS PIN to type on the page.
Cl@ve Permanente: NIE/DNI + password. Some high-security pages also send SMS (needs advanced registration).
QR code and verification code belong here. They are not a third identity.
How to register
You need the TIE support number (top right, starts with E), a Spanish mobile number, and an email.
- clave.gob.es → Registration
- Foreign ID (NIE)
- NIE, support number, phone
- Confirm, then you can use Móvil and/or set a Permanente password
If that fails: Social Security, tax office, or some town halls, with TIE + passport. How to register
New TIE = new support number. Update Cl@ve or login fails.
What it is for
Login and look-up: taxes, social security, many appointments, empadronamiento where the town allows it, DGT. Not the signed Mercurio extranjería packet.
Check lote
Cl@ve does not tell you if the card is ready. https://sclt.es/tie/consultar/ — what lote is. SCLT is the check page; figures follow official data. ICP itself is often down for maintenance.
