Ask HN: Help with my CAPTCHA woes

Hi guys,

I currently work for an organisation who are quite security conscious and implemented CAPTCHA across various login screens on our sites a couple of years back.

Our CAPTCHA is quite easy to read but I can still see from customer feedback and statistics that they are a source of irritation to our users and have actually in some instances even caused customers to cancel accounts!

Our dev manager understands the need to get rid of the CAPTCHA's on the site but refuses to do so unless someone can come up with a solution that will prevent automated logins.

Has anyone got any suggestions?

Thanks
