What is one way an organization can enhance its security in ArcGIS Online?

Enabling two-factor authentication (2FA) is a robust method for enhancing an organization's security in ArcGIS Online. This measure adds an additional layer of protection beyond just a username and password. With 2FA, even if user credentials are compromised, unauthorized access can be prevented since an additional verification step is required.

When implemented, 2FA typically involves sending a unique code to an already established mobile device or email account when logging in. This approach significantly reduces the risk of unauthorized access due to phishing attacks or password breaches, thus safeguarding sensitive data and maintaining the integrity of the organization's resources.

In contrast, the other options — such as disabling user permissions or removing privacy settings — may inadvertently lead to a reduction in security rather than an enhancement. Limiting access to only public data does not address security for private information and could hinder collaboration within the organization. Therefore, two-factor authentication stands out as a proactive and effective strategy for improving security measures in ArcGIS Online.
