February 2020 Chrome 80 update - a third party cookies stopped working causing major online application issues - Am I affected?

Starting from Chrome version 80, most of on-line appications using third party cookies possibly stopped working properly. This isssue is due to enforced in February 2020 more strict regulations regarding 3rd party cookies used by developers. Some of appliactions suddenly stopped working after automatic browser update.

This problem might be more onerous because Mozilla and Microsoft have also indicated intent to implement the new model in Firefox and Edge, on their own timelines.

Am I affected? Who is facing third party cookie security upgrade?  

If you are not sure whether your app is working properly or you are using online service which is not working as it supposed to work you may use our on-line browser test for third party cookies support. This test is free with results in seconds.

According to the online traffic monitor StatCounter, Chrome is the most popular web browser, and this change will affect 64% of the world’s internet users in 2020. 

Why we are facing this issue?

The answer is: a privacy. In October 2019 Google has announced changes that it'll be making over the next two years with the ultimate goal of phasing out support for third-party cookies in Chrome altogether. The new plans by the firm were sparked by people’s desire for greater privacy and control over their data.

The plan to force third-party cookies onto HTTPS was first revealed in May 2019, this forewarning should have given website admins time to update their website to ensure that no problems occur with the launch of Chrome 80. 

Websites typically integrate external services for advertising, content recommendations, third party widgets, social embeds and other features. 

Only cookies with the SameSite=None; Secure setting will be available for external access, provided they are being accessed from secure connections. The Chrome Platform Status trackers for SameSite=None and Secure will continue to be updated with the latest launch information.

Chrome's Changes Could Break Your App

Now, the day is finally at hand. Starting February 4, 2020, Google Chrome will stop sending third-party cookies in cross-site requests unless the cookies are secured and flagged using an IETF standard called SameSite.

Today, if a cookie is only intended to be accessed in a first party context, the developer has the option to apply one of two settings (SameSite=Lax or SameSite=Strict) to prevent external access. However, very few developers follow this recommended practice, leaving a large number of same-site cookies needlessly exposed to threats such as Cross-Site Request Forgery attacks.

What does this mean? What are third-party cookies? What are cross-site request?

When you visit a website, a browser cookie is generated and saved inside a folder in your web browser. This browser cookie is then used as a way to identify you and provide a personalized browsing experience.

There are two types of cookies — first-party and third-party. Both types can hold the same information; however, they are accessed and created differently.

Is it easy to fix it quickly?

Unfortunately not. There are multiple complex things to be fixed and patched. Please also note that cookie warnings triggered from domains you don't control will need to be set appropriately by the domain owner. If you are getting a warning like this from Google, Google will have to set this cookie appropriately. If the warning messages list a domain you control, you will need to add the correct attributes.
