This is coming from a conflict with your template and our css.
Your template has a style
.uk-checkbox, .uk-input, .uk-radio, .uk-select, .uk-textarea, .uneditable-input:not([class*=uk-]), input[type=checkbox]:not([class*=uk-]), input[type=color]:not([class*=uk-]), input[type=date]:not([class*=uk-]), input[type=datetime-local]:not([class*=uk-]), input[type=datetime]:not([class*=uk-]), input[type=email]:not([class*=uk-]), input[type=month]:not([class*=uk-]), input[type=number]:not([class*=uk-]), input[type=password]:not([class*=uk-]), input[type=radio]:not([class*=uk-]), input[type=search]:not([class*=uk-]), input[type=tel]:not([class*=uk-]), input[type=text]:not([class*=uk-]), input[type=time]:not([class*=uk-]), input[type=url]:not([class*=uk-]), input[type=week]:not([class*=uk-]), select:not([class*=uk-]), textarea:not([class*=uk-]){
font:inherit;
}
If I add a style for that input for font-size:initial, the text is readable again.
If you add the following to your theme for SCLogin, you should be set:
.sourcecoast .input-append input, .sourcecoast .input-prepend input {
font-size: initial;
}
