What is OTP?

OTP as digital signature:
OTP-based digital signatures are designed to give greater legal validity to documents signed electronically and optimize processes. At present, more and more companies are using this system for the authentication of signatures on a daily basis.
How are these codes for digital signature generated?
OTPs are generated from the hash of a file, which is an alphanumeric sequence of identification, so that the OTP code is directly linked to the document to be signed. This key is sent to the user to their mobile device and, later, they must enter this code to the digital signature platform to carry out the procedure. By using a mobile phone to send the code, it is most likely that this number must be linked to the identification of the user who wishes to sign and, once again, avoid identity theft. It is timely to point out that an OTP code for digital signature is sent exclusively to the person who is going to sign and that it lasts only a few minutes to increase security.

Save time: the signing process is extremely fast and can be done at any time and from anywhere in the world.
Save resources: compared to the traditional method of sending documents to be signed, resources are saved, since it is not necessary to spend on mailings or printing sheets.
It is unalterable: this code and the signature that is made later, have a specific date, time and destination number. All this data cannot be altered or deleted, so there is a clear record of the user's movements.

Other dual-factor systems could be facial recognition, the use of a fingerprint, a code received by SMS, and even a physical device that works as a key. The most common is to use an application on the mobile phone , which is where the codes are generated and they change every twenty, thirty or sixty seconds, depending on the app .
To configure them, you must first activate the double authentication factor in the desired account or tool (for example, Gmail, Instagram or Twitter). This generates a QR code that must be scanned from the mobile OTP application for the account to be linked. Once this is done, every time you want to log in to said platform, you will be asked for, in addition to the main password, this one-time key that expires in a few seconds.
