MSSpray is an archived Python 3 utility that uses legacy ADAL resource-owner password credentials (ROPC) to test one password against a user file or check one test credential across a built-in list of Azure and Microsoft 365 endpoints. It is no longer developed; Microsoft discourages ROPC, and the tool's first listed Azure AD Graph endpoint was retired in 2025. The source writes returned tokens to local logs, so use only disposable credentials in an isolated, authorized test tenant.
