Secure the signing of contracts with SMS

Coffreo, France's leading provider of paperless HR services for employees, has opted for SMS to communicate its innovative electronic employment contract signing service.

What is Coffreo?

Coffreo specializes in online HR document management and security for companies. It offers digital solutions designed to simplify the administrative management of human resources by automating the processes involved in managing contracts, payslips and other employment-related documents. With several tens of thousands of contracts dematerialized every month, Coffreo has become thebenchmark operator for electronic employment contracts.

What type of SMS does Coffreo send?

The company has opted for communication via SMS for both parts of a contract. Firstly, Coffreo informs employees of the receipt of a new employment contract by means of a mobile alert message (the employee knows that he or she has a new electronic employment contract to sign). Next, Coffreo enables the contract to be signed electronically using a SMS OTP, a unique code sent to a verified telephone, which can be completed on the platform to confirm the signature.

How SMS secures the electronic signature of your contracts

SMS guarantees the confidentiality andlegal security required for this service. The employment contract is accessible 24/7 via the Internet, and is signed by entering a signature code, also sent by SMS, once the terms of the contract have been accepted.

When a person wishes to sign a contract electronically, a strong authentication method is required to verify his or her identity. This method is based on a two-step proof of identity:

Entering a verification code: A unique code, also known as an OTP code (One-Time Password), is sent by SMS to the signatory's telephone number. This code, which is temporary and valid for a limited time, must be entered in the electronic signature interface to confirm the identity of the signatory.
Link between signatory and document: By requiring this code to be entered, the signature system creates a secure connection between the signatory, the document to be signed, and his or her telephone number. This process greatly reduces the risk of fraud by confirming that the person is in possession of the telephone linked to their identity.
