User ID PIN Validation

Your certified validation with operation codes via SMS

Send and validate with One-Time Password (OTP) Codes

Sending single-use numeric codes (understood as passwords sent through an Interposed Trusted Third Party) avoids document tampering so they can be used as evidence in a trial.

Send and validate with One-Time Password (OTP) Codes

Do you know how it works?


You ask for an OTP Code via SMS, providing us with the user’s data.


We provide the request with a qualified time stamp.


We generate and send the OTP Code via SMS to the user in charge of entering it on your website.


You send us the code entered by the user and we verified that’s the same code sent to his mobile.


After the validation, we issue a certificate with the process data and result, keeping the original and the generated evidence.

Access Authentication

There is evidence of the date and time of access generated by a third party.

Secure Access
