captcha is really hard to read

Open rhaamo opened this issue 3 years ago • 12 comments

I've stumbled on a lot of captchas generated which are really hard to read like:

using retry leads to some readable but it's really easy to trigger a "too many requests" and captcha not updating anymore.

Current rate limit for captcha is 10 Captchas every 60 seconds. The chance that all of them are impossible to read is very slim. Captchas are purposefully hard to read, so OCRs can't read them with an algorithm. Additionally, you only need Captchas for registering with email, login with email and reporting a user. Since login with email now has a remember me function, so the number of cases where you even need a captcha.

Leaving this issue open to see if more users feel this way.

Those captchas are literally unreadable to me, I don't want to get blocked out of an account because I don't have a perfect eyesight and good deduction skills.

Actually you don't even need any captchas if you register and login with OAuth.

Which would need me to use OAuth, something I'd avoid for obvious privacy reasons (and the need for an extra step: creating an account of the dangerously cancerous and unsecured platforms known as Facebook and Google).

I think the captcha is easier to read in Light Mode, because of how the human eye works (the color of the current captcha should be a perfect grey so it is readable in light and dark themes).

It isn't, to some people (including me), light theme or dark theme won't change it.

More users defs feels this way, both my friend and I have trouble with the captcha

I too was surprised by the difficulty of these captchas. Yet, it usually goes right when you just go with gut feeling, which I guess is kinda the point.

Why not using https://mcaptcha.org/ ?

@Thatoo Correct me if I'm wrong, but mCaptcha doesn't look like a real "captcha" to me. It's more or less a rate limiter (which already exists for Alovoa) by forcing the browser to solve a math problem in the background, which computers excel at, not humans. It's possible for someone with a strong enough computer to solve the "captcha" within milliseconds.

It works more or less like reCaptcha et hCaptcha, based on Proof-of-work but it's open source and it respects privacy (no tracker and no IP collection). That's all I know. I see reCaptcha being used everywhere which is not good because it's Google behind it and it serves Google to track users. So if we can have an open source none tracking equivalent to reCaptcha I guess it's good but I don't know much more than that.

@Thatoo There is a good discussion on hacker news https://news.ycombinator.com/item?id=32340305 If it were to act like reCaptcha or hCaptcha there would be an option to choose images from a 3x3 grid
