anyone knows why reddit doesnt like them using the reddit api?

>We unfortunately do not allow use of Reddit’s API for account authentication with third-party sites or applications that have no partnership, affiliation, or connection with Reddit. Reddit does not offer or support “log in with Reddit” or “use Reddit” to login services. Use of any sort of button, including a “use Reddit” login button like the one currently featured on your site, is unauthorized.

I'm currently on the search for a service to facilitate DDNS. Duck DNS seems popular, but I'm skeptical of things that are simply offered for free. What assurance do we have that Duck DNS is secure, or that it will not just disappear one day? The alternative that seems better to me is Namecheap with their API.

I’m using ddclient [0] with Google Domains. Pretty easy to set up on a raspberry pi.

I remember using it years ago to be able to point from the outside to a dynamic IP.

I used an old Android phone with their app to keep the IP updated. Like the old no-ip but without a PC.

It is a great service - I have been using it for over 6 years now.

one could just pay a small yearly fee to register their domain with google and get easy/unlimited ddns.

I don't believe this solves the issue if your IP changes all the time.

For anyone hosting their domain on Google Domains, there's a neat API endpoint they're offering for updating the DNS with a simple CURL. I've been using this for years now for a public Raspberry PI behind a home router that changes IPs every other day.

  curl -s -k --user "username:password" "https://domains.google.com/nic/update?hostname=yourdomain.com"

There's more parameters (and you can specify an IP, the above request only takes the caller's IP).

Here are the docs: https://support.google.com/domains/answer/6147083?hl=en#zipp...

Maybe I'm missing something obvious, but why not just pay for a domain and run a cronjob to update the IP in case it changes?

It seems unsafe to me to be passing your username and password over the open every second day. Especially one that links to Google - which for the majority of people is their life.

As a side note - will the recent announcement by Google about unsafe logins being denied affect you?

I use Cloudflare, and there are also tons of APIs for update IP of DNS configuration.

In the open? I believe u:pwd is HTTP Basic Auth, which is not "in the open" when over TLS.
