Running R62.16 Build 27.1.62.16 on a Dell Windows 10 PC
Started a few days ago, every time I run One Step update, my BMO Harris account challenges me for MFA. After that, I get an email stating "Your BMO account was accessed by an unregistered device," so it's not remembering my device between update requests. I can log directly into their website without an MFA challenge.
fyi… My problem sounds similar to Express Web Connect with RBC Royal Bank (Canada) and Trusted Device MFA. BMO Harris is a US Bank. It used to be just "Harris Bank" until BMO (Bank of Montreal) took them over years ago. (Don't know if Canada is a common denominator or coincidental)
