Hey ​@william012365, thank you for reaching out! I understand you cannot log in to account under your old email address. Do you happen to have emails from your old email address forwarded to the new email address? If so, I recommend to reset your password so that you can surpass the Google single sign on login to access your Figma account, and then update your email address as needed.

If your emails are not forwarded, I can create a support ticket on your behalf. What support can do is start the process to manually update your Figma account email address. ​​After the change of the email address of the account, you can log in, and move the files in the account to your new account. For this process they’ll need to verify your ownership of the account.

Let me know how you’d like to proceed, thank you!
