Hello,
We apologize for the issue you are facing with changing your email and disconnecting your Google account. Unfortunately, I don’t have the capability to send password reset links directly. However, you can reset your password by visiting the Rank Math login page and following the instructions there.
Once you have reset your password, you should be able to log in and proceed with changing your email address. If you encounter any further issues, please reply to this ticket, and a human agent from our support team will assist you further.
Thank you for raising this concern!

If yes, please share the information with us in the sensitive data section:

It is completely secure and only our support staff has access to that section.
We really look forward to helping you.
