How to: Get double digits in CAPTCHA input

Currently the 40px width of the CAPTCHA on the login modal means that it will only show a single number at a time. If you enter 88, one only sees 8.

In /wp-content/plugins/captcha/captcha.php edit line 3895 (Based on latest version of CAPTCHA at date 2017/09/01)

style="margin-bottom:0;display:inline;font-size: 12px;width: 40px;"

to

style="margin-bottom:0;display:inline;font-size: 12px;width: 60px;"

This should resolve the issue and you will now be able to see multiple digits on capture.

There is a class which these properties can be assigned to but due to this method of declaring a style in the code itself instead of in the style section means it will not inherit those properties.
