Besides Device, which other factor can be used for behavior sign-on detection in MFA rules?

In the context of Multi-Factor Authentication (MFA) rules within Okta, behavior sign-on detection helps organizations determine the risk level associated with a user's login attempt. This approach often relies on various contextual signals to evaluate whether the login attempt is expected or potentially suspicious.

The factor of IP address is particularly significant because it allows organizations to assess the geographical origin of login attempts in real time. By monitoring IP addresses, Okta can recognize patterns associated with user behavior, such as whether a user is attempting to log in from a known, trusted location or from a new or unusual one that could indicate a security threat. This can help in distinguishing between regular user behavior and potentially fraudulent activity.

While the other options—location, username, and time of login—can provide relevant context, the IP address specifically serves as a technical marker that directly ties to the technical infrastructure of how users access applications and systems. It can instantly signify any abnormalities like an attempt to log in from a different country, thus raising alarms and triggering additional authentication steps if necessary.
