Hello,
Thank you for getting in touch with us.
We pull that information from WordPress Dashboard > Users > Your Profile.
Please update that information to your brand or website name to keep your sensitive username from showing up in the Schema.
If you wish to completely disable the Schema (JSON) – which we do not recommend, you can do so from WordPress Dashboard > Rank Math > Dashboard.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
