- Keep the user identified so that, if you leave the website, browser or device and at another time again to access the same page, will continue to be identified, thus facilitating their navigation without having to re-identify.
- Check if the user is authorized to access certain Services or areas of the website.

- Advertising: They are those that collect information about the ads shown to users of the website. They can be of two types:

- Anonymous: They only collect information about the advertising spaces displayed on the website, regardless of the user who accessed the website, i.e., without expressly identifying themselves.
- Personalized: They collect personal information from the user of the website by a third party, for the personalization of these advertising spaces.

- Geolocation: These cookies are used to find out in which country or region the user accessing a website service is located, in order to offer content or services appropriate to their location.

- Analytical: They collect information about the user's browsing experience on the website, usually anonymously, although sometimes they also allow to uniquely and unequivocally identify the user to obtain reports on the interests of users in the services offered by the website.
