An example of permanent authentication cookies: when permission is given for the website to remember who you are or save your data for future access. The tracking function can be activated without knowledge of the user, as they automatically happen.
Therefore, it is important to be careful when allowing cookies to access unsecured channels or clicking on unknown links, as this can lead to an invasion of your computer and possible hijacking of cookies, which may disclose your personal information to strangers. Precisely for this reason, this issue has generated several controversies between groups that defend the privacy and security of users and their data, causing the development of specific regulations in several countries to reach control and avoid possible abuses in the use of personal information. An important regulation recently passed was the General Data Protection Regulation, which came into force in Brazil in February this year, and also Cookies Regulation which has been in force in the European Union since 2011.
As cookies are able to provide a large amount of personal data and are able to identify users without necessarily needing their consent, from a legal point of view, this means a serious breach of privacy.
In consequence, it is interesting to take measures to comply with the GDPR if you are the owner of a website or e-commerce, as failure to comply with the measures established by this regulation can result in fines of up to R$50 million to a total or partial ban of the activities that involve any use of the data.
