/badge.svg "Build)"){kind=icon}
mCaptcha widget should be loaded within an iframe
- The user clicks on the validation button
- The widget(within the
iframe) computes proof-of-work - Sends it to the mCaptcha (backend)instance
- If proof is valid, mCaptcha instance will send a verification token
- Widget sends parent webpage(webpage containing the
iframe) a message containing the verification token - Glue code receives message and embeds the token in a hidden input
field with name and ID
mcaptcha__token
The glue code is responsible receiving and embedding the token and
optionally create the iframe itself.
