Why are you requiring CAPTCHA?
At JSTOR, we are constantly making modifications to the platform to enhance features, improve performance, and better understand our users’ behavior and needs. The intermittent use of CAPTCHA is a way that we address robotic activity and excessive downloading.
What to do when you don't see a CAPTCHA
If you're trying to register for an individual account, you might be prompted to complete a CAPTCHA before your account is completed. But, certain programs, settings on your computer, or even your internet connection can prevent CAPTCHA from displaying or functioning properly.
But, if you need help right away, try a few of the solutions below.
Clear your cache and cookies
A good first step is to clear your cache and delete your cookies. Our Support Page for Clearing Cache and Cookies will show you how to do just that in Chrome, Firefox, Internet Explorer, and Safari.
Disable Ad Blockers
Ad blockers may interfere with CAPTCHA. You can turn off ad-blocker for JSTOR without disabling your ad-blocker for other sites. To disable ad blockers, you can go into the settings for your ad blocker and "whitelist" or "allow ads" for jstor.org, but make sure to check your ad blocker's support site for more instructions.
Change Firewall and Proxy Settings
Other culprits can include your firewall or proxy settings, which are typically set by your institution's library IT department. If you've tried the above and are still experiencing issues, we recommend that you contact them. We'll be happy to work with them to troubleshoot further.
Is CAPTCHA accessible?
Our CAPTCHA provides an audio CAPTCHA for those who need it. You will be asked to listen to an audio file and type the numbers you hear into a form field. If all else fails, please contact us.
