Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
Could you please share the new email address you wanted to use so we can check in our system? You can add it to the sensitive data section

It is completely secure, and only our support staff has access to that section.
Meanwhile, try clearing your website’s cache or logging in to a different internet browser for checking.
Looking forward to helping you.
Thank you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
The email address you shared just now is the current email address for your account and you are currently logged in. It appears that you are only logging in using Google/Gmail. Can you please confirm if correct?
If so, you can retrieve your password by heading over to our login page and clicking “Forgot Password?”, you should be able to reset your password using the email you want.
Please let us know how that goes. Looking forward to helping you.
