On Thursday, Google announced that it will revive the SameSite cookie strategy starting with the July 14 release of Chrome 84, and will gradually deploy it to Versions 80 and above. When Chrome 80 went live in February, Google began rolling out the SameSite update, making a series of new changes to maintain user privacy and security through cookies. In April, Google announced a temporary suspension of the update in response to the global outbreak to keep key websites up and running during the COVID-19 pandemic.
Under this policy, all cookies must be marked with the SameSite value, and the samesite and Lax cookies will be used in the same domain. Website cookies are expected to be used by third-party users, and their cookies must be sameSite , and they must be transmitted in HTTPS. Once Chrome launches the feature, the site will not be able to generate cookies for users who are not in the same domain, nor will it be able to obtain information about the user, such as the device used, what is online shopping, etc.
