Authorizer Examples

Example applications and integrations for Authorizer — the open-source, self-hosted authentication and authorization server.

Authorizer v2 server is configured entirely via CLI flags (no .env / OS env vars), e.g.

./authorizer \
  --database-type sqlite --database-url authorizer.db \
  --url http://localhost:8080 \
  --jwt-type HS256 --jwt-secret <jwt-secret> \
  --encryption-key "$(openssl rand -hex 32)" \
  --client-id <client-id> --client-secret <client-secret> \
  --admin-secret <admin-secret>

All of the above are required as of 2.4.0 — the server exits at boot if any is missing. --url is this server's own address (not the apps allowed to call it, which is --allowed-origins).
