Quick Guide: How to sign a document you received with Cincel

You have received a request to sign a document through Cincel!

Our signing process is designed to be fast, secure, and accessible from any device, even if you don't have an account with us.

Key Points for the Signer:

  • No account needed: It is not necessary to register with Cincel to be able to sign.
  • Unique and secure link: The email you received contains a personal and non-transferable link. Do not share it.
  • Sign from anywhere: You can complete the process from your computer, tablet, or smartphone.

💡 Cincel Tip: We recommend using Mozilla Firefox or Google Chrome for a better experience when viewing and signing your document.

 

Step 1: Open your Email and access the document

  1. Look in your inbox for an email from notificaciones@cincel.digital (Note: the domain may vary depending on the configuration of the sending company).
  2. Inside the email, click on the main button that says View document.

💡 Cincel Tip: The invitation email generally has the following legend: (The creator) ‘has invited you to sign a document. You can use this message as a keyword to start a search’.

Can't find the email? Check your "Spam" or "Junk" folders. If it doesn't appear, contact the person who sent you the document to verify your email address and resend it to you.

 

Step 2: Verify your Identity (if required)

The person who sent the document may have activated additional security measures to protect the document. If so, the platform will guide you step by step. The most common verifications are:

  • Proof-of-life Test: You will be asked to take a photo of the front and back of your official ID (INE, passport, etc.) and then a photo of your face (selfie) to verify your identity. Follow the on-screen instructions for a successful validation.
  • Geolocation: Your browser will request permission to access your location. If it was configured as mandatory, you must accept it to continue with the process.

 

Step 3: Review and Sign your Document

Once inside the platform, take the necessary time to read the document. When you are ready to sign, the platform will guide you to the fields that correspond to you.

The way of signing will depend on what the sender has requested:

 

Option A: If Simple Signature (Handwritten) is required

  • Click on “Sign”

The document creator is the only one with the power to determine which of the two options below is required:

To sign by hand:

  • Use your mouse (on computer) or your finger/stylus (on tablet or mobile) to draw your signature.
  • If you don't like the result, click on Clear to try again.
  • Once satisfied, click on “Sign”.

To sign by typing:

  • Type your name with your keyboard in the “Full name” box. By default, the name used by the sender to identify you as a signer is added; you can edit it as necessary.
  • By clicking “Sign,” you confirm that your written name represents your consent, your signature, and your intent to sign this document.

 


Option B: If Advanced Electronic Signature (e.firma) is required (Mexico only)

  • You must have your valid e.firma files (formerly FIEL) issued by SAT at hand.
  • Click to upload your Certificate (.cer).
  • Click to upload your Private Key (.key).
  • Type your private key password in the corresponding field.
  • Click on the Sign with e.firma button.

 

Step 4: Finalize the Process

Done! Your part is finished. Once all parties have signed the document, you will automatically receive an email with a pdf of the final document, fully signed and certified, for your records. Remember that in the platform you can also download all the legal backups of the document you have signed.
