I am getting a message: "You have blocked third-party cookies in your browser". What does it mean?

Q: Hello! I got the following message when using Safari:

You have blocked third-party cookies in your browser. Authorization requires third-party cookies at least for social.uploadcare.com domain.

Is this something that can be solved by using custom OAuth?

A: Custom OAuth can be used when you want your users to give permissions to your app, not Uploadcare’s to reduce surprises or hide the fact that you’re using Uploadcare.

All uploads from social networks and cloud storage services are still going through our servers. And as we need cookies to tell authenticated users from unauthenticated, custom OAuth does not affect the requirement.
