A digital certificate is like an electronic DNI that allows you to identify yourself when carrying out a digital transaction, especially on pages where very sensitive information is handled such as the Treasury or the city council of your city.

It is a document that contains all kinds of data that allow you to prove that it is you and not someone else who is requesting an online procedure. Also, it is much more secure than a password as it is encrypted, unique, and has to be installed on a device to work.

It is issued by a certifying authority, so it is not something you can generate on any website after searching in Google. In the case of Spain, the digital certificate is generated by the National Currency and Stamp Factory (FNMT) and allows procedures to be carried out with multiple State institutions.

Why is the digital certificate important? We already mentioned it above: because only you can use it, because legally it is as valid as a face-to-face signature and because it will save you time and money. All three things are relevant, but in today’s world context perhaps the one that matters most to you is the last one.
