With Alpha Five, creating a captcha is easier than reading one

Everyone's familiar with captchas. Even if you don't recognize the word, you've encountered them.  

The captcha is that distorted image of letters and numbers that you have to type in correctly before you can enter some websites.

The captcha, invented in 2000, makes sure that only humans (as opposed to automated software) are entering a site. Most IT guys know why captchas are there.

But what does the word stand for? I found out when UberFacts decoded the acronym in a recent tweet:

I shared this with my colleagues, and found out that none of them knew exactly what it stood for. But one thing everyone agrees on is that some captchas are pretty darn hard to decode and enter correctly. In fact, if you type "captcha"  in Google, you'll find that the suggested search is "how to avoid captchas." That got me thinking. Could you create a captcha with Alpha Five? And if you can, is it just as hard for developers to create as it is for users to decipher?

It turns out that not only is it possible, but it's easier than I thought. The option to generate captchas is already built into the dialog component. You've probably even seen it before. You simply check the box that is appropriately labeled, and a captcha will be enabled for that field.

So, if you're using Alpha Five, it's easier to create the captcha than it is to read it! Did you know what captcha stood for before this post? Let us know in a comment!
