I always use a VPN to protect my data while accessing the Chase.com website over public WiFi access points. Using the VPN resulted in Chase's security rules getting triggered and my checking and savings accounts being closed. Apparently, my IP address changed to often for them and they flagged the account.
I received NO PRIOR EMAILS OR Phone call from the chase Fraud department, they just closed my accounts.
So, if you are smart enough to protect you banking transaction by using a VPN Encrypted connection, be warned that it may result in all you accounts being automatically closed.
Worst experience I have ever had.
