Pros and cons of using shared vs. private Google Cloud Projects for OAuth

Google Cloud Projects provide tools that enhance business capabilities, including the integration of APIs for email, calendar, and contacts. A key decision for companies using these services, like Nylas, is whether to use a dedicated Google Project or a shared third-party project, especially when leveraging OAuth and scope grants. OAuth is a protocol that allows applications to access user data securely, while scope grants define the level of access. Opting for a dedicated Google Project offers benefits like enhanced security, privacy, system availability, and control over brand identity. It also avoids potential vulnerabilities from shared projects, such as dependency on third-party verification status and possible service disruptions. Conversely, shared projects reduce management overhead and expedite the time-to-live process, which can be advantageous for smaller applications or those with simpler use cases. However, shared projects may compromise custom branding and long-term strategic flexibility, making it imperative for organizations to weigh their options carefully based on their specific needs and objectives.
