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.

Captchas no longer working is a systemic problem that currently affects all of web development.

Interestingly, one of the best solutions I've heard of so far came from somebody right here who is new to PHP. Our very own John Paul. He suggests firing off a confirmation email whenever somebody fills out a contact form so that they can verify that they aren't a bot - either by being asked to submit a random code or clicking on a confirmation link.

Can anyone see anything wrong with that idea? I can't.
