Hi,
I Would like to assist you to change the keys for social media login and sms APIs.
We can do that over TeamViewer and will share the screenshot ans steps so that you can do that in future as well.
Usually developers put the keys at single place only and uses that on all pages so if that's the case then would be a quick and simple task.
I am expertise in php with 7 plus years of experience in IT.
Thanks,
