Security Code is a password credential that is used for secondary authentication. This credential, which is similar to a one-time password, is a randomly generated numeric or alphanumeric string, which is valid for a configured duration. Consequently, this type of authentication lowers the chances of relay attacks.
Security Code can be delivered to an end user through an email message, voice message, or SMS. Tenants can decide on one method of delivery for all users or they can enable users to choose a method of their choice. The email ID and telephone numbers are collected from end users at the time of enrollment.
