ReCaptcha API v2 Styling

由 瘦欲@ 提交于 2019-11-27 02:55:17
I have not had much success finding how to style Google's new recaptcha (v2). The eventual goal is to make it responsive, but I am having difficulty applying styling for even simple things like width. Their API documentation does not appear to give any specifics on how to control styling at all other than the theme parameter, and simple CSS & JavaScript solutions haven't worked for me. Basically, I need to be able to apply CSS to Google's new version of reCaptcha. Using JavaScript with it is acceptable. Overview: Sorry to be the answerer of bad news, but after research and debugging, it's

When the bots attack! [closed]

What are some popular spam prevention methods besides CAPTCHA? I have tried doing 'honeypots' where you put a field and then hide it with CSS (marking it as 'leave blank' for anyone with stylesheets disabled) but I have found that a lot of bots are able to get past it very quickly. There are also techniques like setting fields to a certain value and changing them with JS, calculating times between load time and submit time, checking the referer URL, and a million other things. They all have their pitfalls and pretty much all you can hope for is to filter as much as you can with them while not

How to use GMail as a free SMTP server and overcome captcha

由 六眼飞鱼酱① 提交于 2019-11-26 20:29:18
问题 GMail can used as a SMTP server. I've written the code that does it. But as we all know GMail may occasionally authenticate using captcha ( image verification as they call it). The same thing may be the cause to reject SMTP authentication. As I've seen google shows image verification when you try to log-in for the first time from some machine. All consecutive log-ins from the same machine (to the same account) use regular login. I'm a bit afraid this captcha may also come up again for some

问题 I have a Wordpress blog and the only user input is the commenting system. I want to totally avoid spam comments. Wordpress comes with Akismet but I can also use Captcha. Which plugin/method should I use? My client doesn't mind users entering verification strings to post comments. If I adopt either Akisment or Captcha will I be able to completely control the spam? Is it possible to use either Akismet or Captcha for a simple 4-digit verification? If not then please also recommend a plugin

Selenium and non-headless browser keeps asking for Captcha

问题 I was running into an issue in which one of our sites kept asking for captcha in headless mode in a browser in the cloud, so I switched it to non headless, so I could enter the captcha myself, and I thought the next times it would work, perhaps because some cookies would be stored already, but it didn't even though I entered the captcha several times. Also it's worth mentioning that it runs just fine locally in whatever mode, and it also runs well in the cloud for the non automated version,

问题 I'm getting problems with spam entries in my database through signup form. I have tried many open source Captcha solution, but still facing same problem. I am therefore looking for an alternative solution. What about the solution, where users would have to input the answer to a question? The answer to the question will be a server-side specific word then would this surely defeat a spambot? Would it be better to have a series of simple randomized questions or something like "6 + ? = 9" be

问题 Has anyone been able to successfully prevent spam on their site without placing a burden on your visitor (e.g. CAPTCHA) and without using a centralized spam reporting system (e.g. Akismet) I've found this & it looks promising, but doesn't contain detailed deployment instructions. I want to present my web forms without burdening my users with CAPTCHA like technologies, but also actively automate preventing spam. There doesn't seem to exist a detailed instruction/tutorial on how to implement
