- I make websites
- I’m okay with extreme solutions, like requiring everyone to have a Yubikey-or-similar physical key
- I really hate the trend of relying on a phone number or Google capcha as a not-a-bot detection. Both have tons of problems
- but spam (automated account creation) is a real problem
What kind of auth should I use for my websites?
mCaptcha is a proof of work pseudo-captcha, it won’t block bots completely, but it heavily rate limits them and makes them computationally expensive to run.
Benefits - costs: If your benefits from having less spam and the work they are doing by solving the task are greater than your costs this is acceptable.
