Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Feel free to connect your account to that website while you develop the website. When you finish the project, you can disconnect your account by heading over to WP Dashboard > Rank Math > HELP and removing the website from your Rank Math account by visiting https://rankmath.com/my-account/websites/.
Later your client can connect Rank Math account with the website.
None of the settings will be lost because all the settings will be stored inside the database.
I hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
