What is sig?

The authentication layer for AI agents and scripts. Authenticate via browser SSO or OAuth2 Client Credentials, then any tool can access your work systems — Jira, Slack, wikis, APIs — without storing passwords. Credentials are encrypted at rest and injected on demand.

Four ways to use credentials

sig get

Get credential headers for your own HTTP calls

sig request

Make authenticated HTTP requests directly

sig run

Inject credentials as env vars into any command

sig proxy
