If you would like to change your password, please navigate to the password reset page here.
Once you request a new password, an email will be sent to you from do-not-reply@poloniex.com with a link which will lead you to a page where you will be asked to set a new password.
Should your IP change during this period, the password reset procedure will fail. If you are experiencing this, please disable your VPN or anything that could cause your IP address to change unusually quickly.
If you cannot change your password using this process, please contact our support team for assistance.
