One thing I have started doing is using a VPN with the location set to my home location 100% of the time when home. Then, when logging in abroad I use the VPN to my home location. It seems that using the VPN 100% of the time has trained many of these smart services to fingerprint that as my default fingerprint. Of course, this doesn't help when interacting with services that detect/block VPNs. Or the even more annoying situation where VPNs are blocked and also all traffic from the country you are in is also blocked (occurs occasionally when trying to access US sites from SE Asia) edit: WRT comments mentioning that you can call your bank or set a travel notice: that is how things used to work. Chase, for example, no longer lets you set a travel notice as they use a "smart" automated system. That said, my Chase travel card used via apple/android pay has never given me trouble so their system does seem better than most
