It is for creating Apple and Google login credentials, configuring callback URLs, setting up Apple services and keys, and connecting Google Play Console with Google Cloud.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

social-auth-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Social Auth Setup (Apple + Google)

Overview

Both providers require setup in three places:

  1. The provider's developer console (Apple Developer Portal / Google Cloud Console)
  2. Supabase Auth settings
  3. Mobile app (app.json + Expo config)

Sign in with Apple

Step 1: Enable Sign in with Apple on the App ID

  1. developer.apple.com/account/resources/identifiers
  2. Click your App ID (the one matching your ios.bundleIdentifier)
  3. Scroll to Sign in with Apple → Enable → Edit
  4. Leave as "Enable as a primary App ID" → Save

Step 2: Create a Services ID (for web/Supabase callback)

This is separate from your App ID — it's used for the OAuth redirect flow.

  1. Identifiers → + → Services IDs → Continue
  2. Description: Your App Name Sign In
  3. Identifier: com.yourorg.appname.siwa (convention: bundle ID + .siwa)
  4. Register
  5. Click the new Services ID → Enable Sign in with Apple → Configure
  6. Add your Supabase callback URL:
    • Primary App ID: select your app
    • Domains: YOUR_PROJECT.supabase.co
    • Return URLs: https://YOUR_PROJECT.supabase.co/auth/v1/callback
  7. Save → Continue → Register

Step 3: Create a Private Key

  1. developer.apple.com/account/resources/authkeys → +
  2. Name: Sign in with Apple - Your App
  3. Enable Sign in with Apple → Configure → select your App ID
  4. Continue → Register
  5. Download the .p8 file — one-time download, save it
  6. Note the Key ID (10 chars)

Step 4: Configure Supabase

  1. Supabase Dashboard → Authentication → Providers → Apple
  2. Fill in:
    • Service ID: the Services ID from Step 2 (e.g. com.yourorg.appname.siwa)
    • Team ID: your 10-char Apple Team ID (top-right of developer.apple.com)
    • Key ID: from the key you downloaded
    • Private Key: paste the full contents of the .p8 file
  3. Save

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
