Castellum v0.2.1 — Gmail sign-in fix
Castellum v0.2.1 — fixes Gmail sign-in.
Fixed
- 🔑 Gmail login now completes. The token exchange failed with "client_secret is missing"; Castellum now includes the Google Desktop client secret (the standard, Google-sanctioned approach for desktop apps — PKCE protects the flow and your tokens stay encrypted in the macOS Keychain).
Note for Gmail
If you see "Access blocked: … developer-approved testers", the app's Google consent screen is in testing mode — the developer must add your address as a test user. Outlook/iCloud/Fastmail and any IMAP account work without this.
