How to Recover Your VUCEM Web Services Password (Step-by-Step Tutorial 2026)

Video tutorial: step by step

This video walks you through the entire process in under 3 minutes — from logging into VUCEM to getting your 64-character key:

What you need before starting

• A valid e.firma (FIEL): .cer file, .key file, and password
• Access to the email address registered in VUCEM — the key will be sent there
• Access to ventanillaunica.gob.mx

Step 1: Log into VUCEM with e.firma

Go to ventanillaunica.gob.mx. Select the 'Con FIEL' tab. Upload your .cer and .key files, enter your password, and click 'Ingresar'.

Step 2: Verify your registered email

Once inside, verify your email address is correct — the Web Services password will be sent there. Go to 'Usuarios' menu → 'Cambiar la cuenta de correo electrónico'. Update if needed.

Step 3: Request the Web Services password

Go back to the login page and select the 'Sin FIEL' tab. Click '¿Olvidaste tu contraseña?'. Fill in: Mexican nationality (Sí), RFC type, Persona Física or Moral, your RFC, and your Razón Social exactly as registered. Click 'Recuperar'.

Step 4: Get the 64-character key

VUCEM sends an email with subject 'Envío de contraseña'. Check inbox and spam. The email contains your 64-character alphanumeric Web Services key. Share it securely with your customs broker or configure it in Camtom.

With Camtom, you configure once and forget

Once you have your Web Services key, configure it in Camtom once. From then on, Camtom transmits your MVEs directly to VUCEM — no portal login, no session timeouts, no format errors. Under 3 minutes per MVE, under $60 MXN.
