Implement reCAPTCHA v3
With the recent release of version 3 of reCAPTCHA (the thing you may get to see when you log in and the system suspects you may be a bot instead of a user), it would be a great idea to upgrade to the latest version. We've had several users who have had to fill in the CAPTCHA protection every time for some weird reason (I suspect someone in their neighbourhood is to blame), which could be alleviated with the new system. The system now gives you a score between 0 and 1 to gauge how trustworthy the request is. That also means you can alter how strict the system will be.
The only downside of this means that you'll need to figure out what you'll do with people/bots with low scores. The reCAPTCHA v3 manual suggests requiring two-factor authentication or e-mail validation from such users, which would indeed help against wrong passwords, but probably won't protect the Waze map from scrapers (I suspect that is also part of the reason why the captcha was implemented).
Either way, I think it would be a good idea to already add some v3 calls in the background without adjusting any behaviour, just to get an idea of what scores the system generates.
