How to reduce the Recaptcha difficulty?

I use RecaptchaControl, and the users complain that the image is not that clear (the black part in the the captcha is too hard to read). Is there any property to make the image less difficult (less noisy)?

 <recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="XXX" PrivateKey="YYY" OverrideSecureMode="true"  />

How do I change my reCAPTCHA settings?

Settings Navigate to the settings category. Security & Membership -> Protection Under , select a . CAPTCHA settings Control to use Save the settings. When you change the CAPTCHA type, all web parts and features that have CAPTCHA enabled use the new type.

How do I increase my reCAPTCHA score?

Logging into a Google account improves your score quite a lot, but this also means that Google learns what sites the account owner uses, both on the site with captcha and on sites with unrelated Google services, which use the fact that you are logged in. So it would be good to increase the score without logging in.

Why am I failing the CAPTCHA?

Sometimes, you may see a "failed reCAPTCHA check" error message while trying to create or amend your account. This means the website believes your actions may be those of a bot. Don't worry, it is programmed to be over-cautious for your security.

To put it simply, no.

As others have said you can only customise the UI.

I'm the author of the article about the recaptcha API tutorial @web-development-blog.com and must say it's often very hard to read the text created images by recaptcha. While using the API I got sometimes better results while using a different language for the challenges.

In one of my projects I got a lot of complains and switched to a different script: http://code.google.com/p/cool-php-captcha/

The challenges are less hard to solve and the script is very easy to use.

Possibly not what you are looking for but there are lots of custom captcha controls out there i.e.

CaptchaNET_2.aspx

With a bit of knowledge of the Graphics classes in C# it isn't a hard job to tweak the code to make the captcha simplier (or harder). We use one for a mobile phone web site and control is important otherwise it is unreadable in lower res phones
