I had this problem domestically recently. Chase has my landline # on my account. I was trying to log in on a my laptop from a new location. I finally called THEM (that's one of the options). That was her solution for when I go to Europe: call them collect. Phooey on that. Collect calls in Italy are a nightmare, un vero incubo. I asked if I'd have to re-verify on this same computer every time I was at a new IP address, and she said yes. But it hasn't worked that way this trip. I've used two new internet services and not had to re-verify. Maybe I'm good for the device now.
