Let's get some understanding of how MFA works on a shared workstation functions:

Your member logs into one membership in online banking and uses MFA and registers their device so that they don't need to use MFA the next time they log in (as allowed by your credit union configuration). Then on the shared workstation that member (or another member) logs into a separate membership and also uses MFA and registers their device. It is working as expected if MFA is required when the member logs into the account, even though that first member registered their device.

Some workarounds so the member does not need to use MFA each time (unless required by your credit union configuration):
  • When MFA is used on the second membership, do not register the second device. This way, the first device will remain registered (as long as is permitted by your credit union MFA configuration).
  • Some browser applications have features that support multiple users. These features can be used to allow members to select to log into online banking under their own browser profile.
  • Separate browsers can be used by each user.
