As a more advanced method of securing your Bitfinex account, we recommend for you to enable IP address whitelisting.
IP address whitelisting limits access to your account based on your IP address. You can choose to specify either a specific IP address or an IP range.
Examples - one entry per line; use hyphen to specify range
192.168.0.1
192.168.0.0-255
Important: You can lock yourself out of your account if you are not careful using this feature. Please be sure you are on a static IP address (most users are not!) and that you understand this feature.
To ensure a static IP address, you will most likely require a VPN with a dedicated IP address. Using a regular internet provider, there is no guarantee that your IP address won’t change, locking you out of your account.
If you do not understand this feature, please do not attempt to enable it.
