In February 2020, Google released Chrome 80 and began rolling out new cookie behavior. Details of this change and Google’s rollout plans are available at https://www.chromium.org/updates/same-site.

This change requires cross-site cookies to explicitly declare themselves with the SameSite attribute. Cookies that do not do this will result in a Chrome warning in the developer console and being ignored (not sent with any applicable requests).

All Stripe products (i.e. Elements, Checkout, etc.) that use cookies accessible across sites have been updated and will function the same as before the Chrome 80 release.

However, there may still be some stripe.com cookies set by the Stripe Dashboard, Support Site, or home page that will trigger the Chrome warning on other sites that include the Stripe.js library. We will continue to work at reducing/eliminating these, but these remaining instances do not impact any functionality of Stripe products and only result in a benign warning in the developer console.
