Hello everyone
I'm writing this post in regards to the imminent deprecation of "third party" (i.e.: cross-site) cookies in browsers like Chrome and others.
My company has developed several custom visuals that make web requests to our backend services in order to fetch data.
Of course these calls rely on cookies to make sure users are authenticated on our backend services and properly authorized.
Until now, this was possible without issues. What we did in our visuals until now is this:
Thanks to the "WebAccess" privilege, that allows us to make cross-site requests to specific domains without any problem, this worked perfectly until now. However, the new policy in Chrome and other browsers will soon break this mechanism, as Chrome itself lets you know:
Now, in their guide here, Google suggests various alternatives to third-party cookies, but from my preliminary research and tests the two main ones do not seem promising:
I cannot find much info on this error but, like the problem with the CHIPS method, it seems to be related to the fact the the Custom Visuals iframes are sandboxed and configured so that a call to window.origin returns null.
Now, can anyone tell me if I did something wrong, or am I correct in what I just wrote? Am I missing something? Are the ways to implement one of those two approaches in a PoweBI custom visual?
If the answer is no, does anyone know of any alternative solutions? The only thing I can think of is using the recently introduced option to access the local storage from a Custom Visual to store an authentication token (for example: JWT). However, this is not as straightforward as it sounds, because we must first ACQUIRE the authentication token somehow. I've thought of some hacky workarounds, but nothing that sounds like a proper solution. Does anyone have any better ideas?
Thanks in advance for your support.
Solved! Go to Solution.
Just in case someone else is having this question: I spoke with Microsoft tech support, and unfortunately they say there is no way around this and no further implementations will be done to alleviate this issue.
The only other option is using the authentication API, but be aware of the fact that it is only available for certified visuals and also is only compatible with backends that use Entra ID authentication.

Is there really nobody that is facing this same situation? Really? I'm kinda surprised by that.
Do you think I should open a ticket to MS about this? Can anyone tell me where it would be approriate to do it?
