Which sites/domains do I whitelist so my students can access all of Khan Academy?

Many students, as well as a few teachers and parents who try to contact the Help Center never get a confirmation message. If this has happened to you, your email is either restricted or you have made a spelling mistake when entering your email address. This article deals with restrictions. If the email address was misspelled, you'll need to write a new request with the correct address to receive an answer.

If your browsers are blocking cookies from Khan Academy, the site may experience issues. For information about allowing cookies, check out this article. You'll also need to make sure that iframe access ("content from another origin") is enabled for any browsers being used on the devices that your students are using.

Question: 

• Our students have email addresses but can only receive emails from approved domains. Which domains do I need to add as exceptions for our students to receive emails from Khan Academy?

Answer:  

• khanacademy.org (a variety of senders within that domain)
• khanacademy.zendesk.com to be able to log into the Help center and send Help requests

Question:

• I'd like to whitelist (remove viewing restriction to) the Khan Academy website so that all the material is available to my students. Which domains should I allow access to?

Answer: 

• khanacademy.org
• kastatic.org
• kasandbox.org
• ka-cs-scratchpad-audio.s3.amazonaws.com
• youtube.com
• youtube-nocookie.com
• googlevideo.com

Note: If your students log in via Google or Facebook, you also need to whitelist the URLs for the respective login pages (for the Google app engine).

I also encourage you to visit Khan Academy Access Check— our check site! This page does a quick and automatic review of common network issues that might be keeping you or your students from accessing the full Khan Academy experience. It checks browser compatibility, cookies, iframe access, both the YouTube and Khan Academy video players, and can pinpoint any issues with these. It also really helps our Support team troubleshoot and investigate cases further!
