Steps to Reproduce

Actual Results

The "Log In" form contains a CAPTCHA image. As a result, information conveyed by the image is not available for screen reader users. Screen reader users and users with low vision will be unable to enter the captcha and submit the form.

Expected Results

Since it is not possible to create a fully accessible CAPTCHA, best practice is to avoid using them. Alternative security methods can be implemented to prevent spam while creating a fully accessible form (e.g. using hidden fields, checking the time taken to fill out the field, etc).
For this we recommend Replacing  the CAPTCHA image with a simple logical question.

Or alternatively provide Captcha with audio or another accessibility option.
