True or False: All members on Slack Enterprise Grid must always log in through SSO.

The statement that all members on Slack Enterprise Grid must always log in through SSO is false. While using Single Sign-On (SSO) for authentication is a strongly recommended security measure, it is not mandatory for every user within the Slack Enterprise Grid. Organizations may have different approaches to identity and access management, and some users may log in using traditional methods or alternative authentication methods that do not involve SSO. This flexibility allows companies to accommodate various security policies and user needs, making it an optional feature rather than a requirement for all members.
