Authentication

Edwin supports OAuth and API keys for model providers. For Anthropic accounts, we recommend using an API key. For Claude subscription access, use the long‑lived token created by claude setup-token.

See /concepts/oauth for the full OAuth flow and storage layout.

Recommended Anthropic setup (API key)

If you’re using Anthropic directly, use an API key.

1. Create an API key in the Anthropic Console.
2. Put it on the gateway host (the machine running edwin gateway).

export ANTHROPIC_API_KEY="..."
edwin models status

3. If the Gateway runs under systemd/launchd, prefer putting the key in ~/.edwin/.env so the daemon can read it:

cat >> ~/.edwin/.env <<'EOF'
ANTHROPIC_API_KEY=...
EOF

Then restart the daemon (or restart your Gateway process) and re-check:

edwin models status
edwin doctor

If you’d rather not manage env vars yourself, the onboarding wizard can store API keys for daemon use: edwin onboard.

See Help for details on env inheritance (env.shellEnv, ~/.edwin/.env, systemd/launchd).

Anthropic: setup-token (subscription auth)

For Anthropic, the recommended path is an API key. If you’re using a Claude subscription, the setup-token flow is also supported. Run it on the gateway host:

claude setup-token

Then paste it into Edwin:

edwin models auth setup-token --provider anthropic

If the token was created on another machine, paste it manually:

edwin models auth paste-token --provider anthropic

If you see an Anthropic error like:

This credential is only authorized for use with Claude Code and cannot be used for other API requests.

…use an Anthropic API key instead.

Manual token entry (any provider; writes auth-profiles.json + updates config):

edwin models auth paste-token --provider anthropic
edwin models auth paste-token --provider openrouter

Automation-friendly check (exit 1 when expired/missing, 2 when expiring):

edwin models status --check

Optional ops scripts (systemd/Termux) are documented here: /automation/auth-monitoring

claude setup-token requires an interactive TTY.

Checking model auth status

edwin models status
edwin doctor

Controlling which credential is used

Per-session (chat command)

Use /model <alias-or-id>@<profileId> to pin a specific provider credential for the current session (example profile ids: anthropic:default, anthropic:work).

Use /model (or /model list) for a compact picker; use /model status for the full view (candidates + next auth profile, plus provider endpoint details when configured).

Per-agent (CLI override)

Set an explicit auth profile order override for an agent (stored in that agent’s auth-profiles.json):

edwin models auth order get --provider anthropic
edwin models auth order set --provider anthropic anthropic:default
edwin models auth order clear --provider anthropic

Use --agent <id> to target a specific agent; omit it to use the configured default agent.

Troubleshooting

“No credentials found”

If the Anthropic token profile is missing, run claude setup-token on the gateway host, then re-check:

edwin models status

Token expiring/expired

Run edwin models status to confirm which profile is expiring. If the profile is missing, rerun claude setup-token and paste the token again.

Requirements

• Claude Max or Pro subscription (for claude setup-token)
• Claude Code CLI installed (claude command available)
