I want to remove captcha and its input field from Forgot password form. Please help me to remove that.
If you prefer to run commands instead of going to admin panel:
Disable admin login captcha
php bin/magento config:set admin/captcha/enable 0
Disable frontend captcha ( If form specific captcha is required then please check the Prince Patel's answer )
php bin/magento config:set customer/captcha/enable 0
