Control: 1.8 Ensure that 'Number of days before users are asked to reconfirm their authentication information' is not set to '0'

Description

Ensure that the number of days before users are asked to re-confirm their authentication information is not set to 0.

This setting is necessary if you have setup 'Require users to register when signing in option'. If authentication re-confirmation is disabled, registered users will never be prompted to re-confirm their existing authentication information. If the authentication information for a user changes, such as a phone number or email, then the password reset information for that user reverts to the previously registered authentication information.

Remediation

From Azure Portal

1. From Azure Home select the Portal Menu
2. Select Azure Active Directory
3. Then Users
4. Select Password reset
5. Then Registration
6. Set the Number of days before users are asked to re-confirm their authentication information to your organization-defined frequency.

Please note that at this point of time, there is no Azure CLI or other API commands available to programmatically conduct security configuration for this recommendation.

Default Value

By default, the Number of days before users are asked to re-confirm their authentication information is set to "180 days".
