If your account username includes a '#', what does this indicate about your login?

The presence of a '#' in your account username indicates that you are using Single Sign-On (SSO). This is a common feature that allows users to log in through an authentication service, typically provided by their organization, instead of entering a username and password specifically for the application. In systems that utilize SSO, special characters such as '#' may be included in usernames to handle special authentication cases or to differentiate SSO users from those who log in through standard credentials.

In contrast, guest users do not typically have a fixed username associated with an account, and administrative privileges do not typically correlate with the use of a '#' in the username. Additionally, logging into a shared account would generally mean that the username is more generic and less likely to include special identifiers like '#', as shared accounts tend to use standard naming conventions for ease of access by multiple users.
