Hi All,

I want to add a simple captcha of 5-6 characters on my admin login page and my contact form submissions for adding a little security from brute force login and bots.
can you please suggest how can I add the same?

I would suggest you forget about using a captcha and have a look at DC's anti-spam module along with Apophis mFactor modules on the Module marketplace

I would think that doing an email verify, two factor authentication, would be a better way to go.
You could use mfactor from the module market.
To me, this would be a more secure route to take on a login page.

As Dan and I have already mentioned above, you would be better off using something else as captchas are not user friendly or that secure but if you insist on using one, here is a link to one you can use with Trongate. It has many examples for various frameworks, I'd go straight to the pure php example.
