Managing Passage

Passage Management Skill

Manage and analyze Passage passwordless authentication resources including users, devices, and passkeys.

API Conventions

Authentication

All API calls use Bearer API key with app ID, injected automatically.

Base URL

https://api.passage.id/v1/apps/$PASSAGE_APP_ID

Core Helper Function

#!/bin/bash

passage_api() {
    local method="$1"
    local endpoint="$2"
    local data="${3:-}"

    if [ -n "$data" ]; then
        curl -s -X "$method" \
            -H "Authorization: Bearer $PASSAGE_API_KEY" \
            -H "Content-Type: application/json" \
            "https://api.passage.id/v1/apps/${PASSAGE_APP_ID}${endpoint}" \
            -d "$data"
    else
        curl -s -X "$method" \
            -H "Authorization: Bearer $PASSAGE_API_KEY" \
            "https://api.passage.id/v1/apps/${PASSAGE_APP_ID}${endpoint}"
    fi
}

Output Rules

• Target ≤50 lines per script output
• Use jq to extract only needed fields
• Never dump full API responses

Phase 1: Discovery

#!/bin/bash
echo "=== App Configuration ==="
passage_api GET "" \
    | jq '{name: .app.name, id: .app.id, auth_origin: .app.auth_origin, login_url: .app.login_url, auth_methods: .app.auth_methods}'

echo ""
echo "=== Recent Users ==="
passage_api GET "/users?limit=20&order_by=-created_at" \
    | jq -r '.users[] | "\(.id[0:16])\t\(.email // .phone // "no-contact")\t\(.status)\t\(.created_at[0:10])"' \
    | column -t | head -20

echo ""
echo "=== User Count ==="
passage_api GET "/users?limit=1" | jq '{total: .total_users}'

Phase 2: Analysis

Passkey Adoption

#!/bin/bash
echo "=== Device/Credential Summary ==="
passage_api GET "/users?limit=100" \
    | jq '{
        total_users: (.users | length),
        with_passkey: [.users[] | select(.webauthn_devices | length > 0)] | length,
        without_passkey: [.users[] | select(.webauthn_devices | length == 0)] | length,
        avg_devices: (.users | map(.webauthn_devices | length) | if length > 0 then add / length else 0 end)
    }'

echo ""
echo "=== Users Without Passkeys ==="
passage_api GET "/users?limit=50" \
    | jq -r '.users[] | select(.webauthn_devices | length == 0) | "\(.id[0:16])\t\(.email // "no-email")\t\(.created_at[0:10])"' \
    | head -15

echo ""
echo "=== User Status Breakdown ==="
passage_api GET "/users?limit=200" \
    | jq -r '.users[] | .status' | sort | uniq -c | sort -rn

Authentication Health

#!/bin/bash
echo "=== Recently Active Users ==="
passage_api GET "/users?limit=50&order_by=-last_login_at" \
    | jq -r '.users[] | select(.last_login_at != null) | "\(.id[0:16])\t\(.email // "no-email")\t\(.last_login_at[0:16])"' \
    | head -15

echo ""
echo "=== Inactive Users (no login in 30d) ==="
CUTOFF=$(date -d '30 days ago' +%Y-%m-%dT%H:%M:%SZ)
passage_api GET "/users?limit=100" \
    | jq -r --arg cutoff "$CUTOFF" '.users[] | select(.last_login_at == null or .last_login_at < $cutoff) | "\(.id[0:16])\t\(.email // "no-email")\t\(.last_login_at // "never")"' \
    | head -15

Output Format

=== App: <name> (ID: <id>) ===
Total Users: <n>  Auth Origin: <url>

--- Passkey Adoption ---
With Passkey: <n>  Without: <n>  Avg Devices: <n>

--- User Status ---
active: <n>  inactive: <n>  pending: <n>

--- Activity ---
Active (7d): <n>  Inactive (30d+): <n>

Anti-Hallucination Rules

1. NEVER assume resource names — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. NEVER fabricate metric names or dimensions — verify against the service documentation or --help output.
3. NEVER mix CLI commands between service versions — confirm which version/API you are targeting.
4. ALWAYS use the discovery → verify → analyze chain — every resource referenced must have been discovered first.
5. ALWAYS handle empty results gracefully — an empty response is valid data, not an error to retry.

Counter-Rationalizations

Common Pitfalls

• App ID required: All endpoints are scoped to an app ID in the URL path
• Pagination: Use limit and page parameters; check total_users for total count
• Rate limits: Varies by plan; check response headers for limit info
• WebAuthn devices: Each user can have multiple passkey credentials registered
