Google Chrome phasing out third-party cookies

[lorenzomilesi]

Hi.

We use dropin.js implementation of v2 API. Recently, Google Chrome started printing to the error console they will be phasing out support for third-party cookies. In our app, only two services are still using these, and one is Dropbox.

I was wondering if someone is aware if Dropbox is going to deal with it in the (close) future, to avoid service disruption when Chrome will finally implement the block.

Thanks

Thanks for the note! I'm raising this with the team to check on this.

Hi,

We don't have any additional updates to provide as of today. Once we have more information to share, we will let you know.

@lorenzomilesi This is currently being investigated and worked on. No ETA yet, but we should have a solution before Google starts the phase out process.

@lorenzomilesi This is proving to be a little more complex than I would have liked mainly because google's proposed solution doesn't have wide acceptance with the libraries we're currently using internally.

I did some tests though and I'm wondering if you could verify if there actually is an issue with 3rd-party cookies after following these steps:

1. Clear all cookies for the domain you're testing on
2. Open up Chrome's settings and search for "Cookies"
3. Select the "Third-party cookies" entry and set it to always block third-party cookies
4. Open a new tab and go to the domain with the dropins chooser on it
5. Open up dropins, go through the login flow and see if everything works correctly.

In my local testing that (surprisingly) still worked fine, but I don't 100% trust it. If you don't have any problems with it on your website that'll be a valuable data point.

Hi @Kevin DBX, thank you for the feedback.

I just tested disabling third-party cookies and browsing in incognito, everything seems to work. I'm able to authorize my application and query Dropbox.  Let me know if you need anything else!
