I use my trusted VPN primarily for the sake of anonymity (to avoid data being collected about my Internet browsing), although I am aware of its security benefit -- traffic encryption. My question, however, stems from an unsubstantiated fear I have of using the VPN when accessing sensitive sites (banking, primary email, billing, PayPal, etc.). When accessing sensitive sites I am not seeking anonymity, in fact, quite the opposite; unavoidably such access requires the exposure of personal information (hopefully under the sound encryption that these sites themselves provide).
Several questions related to my title or umbrella question:
Is it advisable to still use a trusted VPN when accessing sensitive sites?
Does using a VPN in such circumstances jeopardize the sensitive information I'm accessing?
Regardless of whether using a trusted VPN inconsequentially effects such access and surveying, do you yourself switch off your own trusted VPN when accessing sensitive sites?
(I am aware of my persistent use of the phrase "trusted VPN". It does seem quite silly and was likely unnecessary. Also, feel free to critique my understanding of "trusted VPNs", the benefits they provide, and so on. I can only begin to conceptualize how a VPN works, although I do know conflicting views exist on the security and general benefit they provide. I use several other mechanisms to enhance my anonymity and my security, none of which include TOR, as I am under the impression it requires legitimate knowledge of CompSci, a "domain" which is widely foreign to me.)
