Problem/Motivation
Alternative attribute text is required for images to ensure a site meets WCAG accessibility guidelines. When adding an image field to a content type, the alt text field is currently optional meaning Drupal sites often fail accessibility audits until alt text is added to images.
Note: This issue does not relate to images added via CKeditor. It relates to changing the default setting on the image field to require the alt attribute.
Proposed resolution
Let's switch the default setting so that alternative text is a required field when adding an image field to a content type.
Remaining tasks
None! We are RTBC :-)

Original report by @Charles Belov
In Drupal 8, an image field can be defined as requiring alternate text. However, this is not the default. This issue requests making it the default.
Steps:
As admin:
1. Add an image field to the Basic Page.
Actual result: Alternative text check box is not checked by default
Expected result: Alternative text check box is checked by default
Workaround: Check box to allow Alternative text.
Actual result: Check box to require alternate text is not checked by default
Expected result: Check box to require alternate text is checked by default
