What is an OAuth grant?
Glossary · AI agent and machine identity security
Short answer
An OAuth grant is the permission a user or admin gives an app, often an AI tool, to act in another service.
Why it matters
Grants stay valid until someone revokes them. Each yes to an AI tool leaves a grant behind.
What it looks like
A user connects an AI assistant to their mail and files. The grant stays after they stop using the assistant.
