To change email address, go to Settings – Personal information and press Change. You will receive a confirmation code on your old email box. Enter it in the dialogue box.
If you had activated 2FA, the system will request the code from Google Authenticator or the recovery code.
After you enter new email address, it needs to be verified. Please repeat the procedure: Go to your newly set mail box and confirm it by entering confirmation code you received there in the dialogue box. Now your new email address is activated.
