How can I add a dynamic IP address to the "Authorised javascript origins" list in Google Cloud so that I can integrate Google sign-in into my web app?

Question

The IP address of the computer is dynamic. I can copy the IP address, add it to the list of approved javascript origins, and use the Google sign-in option in my web app without encountering any problems. Therefore, I'm looking for a solution that enables the dynamic IP address to be used for Google Sign-In as well. I don't want to manually input the IP address as a URL in the allowed javascript origin.

Any ideas, sticking with this for a while?

If it is possible using ddns, how it to be???

Answer 1

You must use valid domain names only in your approved origins in the OAuth credentials in Google Developer Console.

You could use Dynamic DNS to run a domain name from your computer with dyanmic IP. https://en.wikipedia.org/wiki/Dynamic_DNS

Most domain name providers will work with DDNS. https://www.cloudflare.com/learning/dns/glossary/dynamic-dns/

That domain can then be used for an approved Google sign-in origin for your web-app.
