1. Business Unit Identity Verification - Choose whether Identity Verification uses settings inherited from the parent account or uses settings specific to the business unit.
2. Browser Verification Code Lifetime - Select the time period for the verification code to remain active.
3. Time a browser can be inactive before requiring re-verification - Select the time period a browser can go without accessing Marketing Cloud before requiring a new Identity Verification process. This setting applies only to days of inactivity. For example, if you set this field to seven days, a user only re-verifies their identity if that user does not log in for seven days.
4. Do not require Identity Verification for machines inside the whitelist - If you choose this setting and a user attempts to log in from a whitelisted IP address, the system uses the IP address to verify the user browser. If you choose this setting and the user attempts to log in from a non-whitelisted IP address, the user must verify their identity via email. If you do not choose this setting, the user must verify their identity via email regardless of IP whitelisting status if the Allow machines not on Whitelisted IP Addresses access check box is selected.
