Is a Google account necessary for Google Hangouts to function?

Google Hangouts can function without a Google account because it allows users to connect via links shared by others. This means that individuals can join a Hangouts meeting or chat without needing to sign in if they receive an invitation. This feature is particularly useful for guests or people who may not have a Google account, ensuring accessibility and ease of use. However, having a Google account can enhance the experience by allowing users to access more features, save chats, and maintain a consistent identity across multiple Hangouts sessions.

While educational or business accounts provide additional functionalities and organization-specific features, the core capability of Hangouts to facilitate communication remains available to users regardless of account status. Therefore, it's possible to use Hangouts without needing any specific type of Google account.
