In order to ensure maximum security, email changes linked to your Bitfinex account can only be made manually on our end.
To change the email address, submit a ticket with support indicating your request and our team will assist you with the process.
As a security measure, a 5-day withdrawal hold will be triggered for your account when the change is executed
Note: The new email must not be previously linked to any Bitfinex accounts, even if those accounts are presently deactivated.
