Allowed IP Addresses page enables you to require that all PayPal Manager users log in from computers that you specify; no one can log in from an unauthorized computer.
You restrict access to PayPal Manager to users using authorized computers by specifying the IP addresses (unique identifiers) of the computers.
Only administrators can modify the IP information. If you do not have administrator privileges, you can only view this information here.
To access the Allowed IP Addresses page, navigate to Account Administration -> Manage Security -> Allowed IP Addresses.
Specify up to 16 IP addresses from which users can log in to your PayPal Manager account.
Click Update. A gray notification box appears towards the top of the page confirming the changes. If there are any errors, a yellow box appears towards the top of the page stating the problem.
