Which of the following is not a common factor in adaptive authentication for zero trust?

Adaptive authentication looks at the context of a login, including where they're logging in from—both geographically, and from a network trust perspective, what device they're logging in from, and if the device is configured correctly. In modern, multidevice usage, whether the user has logged in recently from another device isn't as likely to be considered, but if the devices were in different countries it would likely raise a flag!
