When I log onto my bank's website on a new device (be it a new phone or a web browser I haven't used before) it prompts me to send an activation code to my phone or email. I have to enter in this one-time code before it will let me log in.
The next time I log in I don't have to do this, unless something happened like I cleared out all my cookies or something. I may even have multi-factor authentication turned on to where I need to do something else like enter in another phrase or a code from a dongle or something but I don't have to do the verification code through a text message or other means unless something changes to my browser/device situation.
What is the term for this? Most of the ____factor Authentication terms are referring to needing to do something every time, I'm just wondering if there's a term for when you only need to do it on new devices.
