What

A few fixes found while testing the Kinde Python SDK with this starter kit.

  • No more tokens in the logs. app.py was logging the ID token, access token, claims and the user's profile at INFO. Those lines are gone.
  • /api_demo no longer crashes when you're signed out. It returned a 500 error; it now shows the sign-in page like the other pages. The other pages also no longer crash if user info can't be loaded.
  • .env is now in .gitignore. Before, git add . would commit your Kinde secrets.
  • Runs on localhost:5001. Port 5000 is taken by AirPlay on macOS, which returns a 403 on the callback. Also, the app has to be opened on the same host as the redirect URI (localhost, not 127.0.0.1), or the login fails with an invalid state error. .env.example now sets FLASK_RUN_HOST and FLASK_RUN_PORT, so flask run just works.
  • README and .env.example use the right variable names. The SDK reads KINDE_HOST for login (the README said KINDE_DOMAIN) and SECRET_KEY (the README said FLASK_SECRET_KEY). Variables that nothing reads are removed from .env.example.
  • Current SDK and Flask-Session. kinde-python-sdk goes from ~=2.0.8 (which never picked up 2.1 or later) to ~=2.4. Flask-Session goes from ~=0.5.0 to >=0.6.0,!=0.7.0,<1.0.0: 0.6.0 is the first version that supports Flask 3, and 0.7.0 breaks the filesystem sessions this app uses. This matches the range the SDK is moving to in fix(packaging): add flask-session to [flask] extra, drop unused deps kinde-oss/kinde-python-sdk#208.

Testing

In a fresh virtualenv with dummy credentials:

  • pip install -r requirements.txt installs kinde-python-sdk 2.4.0, Flask 3.0.3 and Flask-Session 0.8.0.
  • flask run starts on http://localhost:5001.
  • Signed out: /, /details, /helpers and /api_demo all return 200 (/api_demo was a 500 before), and /login redirects to Kinde.
  • After a simulated sign-in, no log line contains a token or the user's email (before: 4 lines with tokens, 8 with the email).

If you already use the starter kit

Update your .env from the new .env.example, and in Kinde change the allowed callback URL to http://localhost:5001/callback and the logout redirect URL to http://localhost:5001.

Summary by CodeRabbit

  • Setup
    • Updated the local setup instructions and configuration examples to use port 5001, including callback and logout URLs.
    • Added guidance on required settings for Management API pages and on avoiding localhost address mismatches that can cause an invalid state error.
  • Bug Fixes
    • Authenticated pages now consistently display selected user information. The API demo returns signed-out visitors to the logged-out page.

- Stop logging tokens, claims and the user's profile in app.py.
- Fix /api_demo crashing when you're not signed in, and don't crash the
  other pages if user info can't be loaded.
- Add .env to .gitignore so Kinde secrets don't get committed.
- Run on localhost:5001 by default (port 5000 is taken by AirPlay on
  macOS, and the app must be opened on the same host as the redirect URI).
- README and .env.example: use KINDE_HOST and SECRET_KEY, which the SDK
  actually reads, and drop variables nothing uses.
- Require kinde-python-sdk ~=2.4 and Flask-Session >=0.6.0 (Flask 3
  support), skipping the broken 0.7.0.

📝 Walkthrough

Walkthrough

The starter kit updates its SDK environment setup and dependency constraints. Its routes now use shared authorized user data, and the helper no longer logs profile or token details.

Changes

Starter kit configuration and authentication

Layer / File(s) Summary
SDK configuration and setup instructions
.env.example, README.md, .gitignore, requirements.txt
The environment example and setup instructions use SDK v2 variables and localhost port 5001. The README documents Management API settings and localhost address consistency. .gitignore excludes .env, and the SDK and Flask-Session constraints are updated.
Authorized user data in routes
app.py
get_authorized_data no longer logs profile, token, or claims details. The /, /details, and /helpers routes use its returned data when available. /api_demo renders logged_out.html when the helper returns no data.

Merge Risk: ⚪ Minimal · up to 8a247

The update reduces direct sensitive-data logging and its setup is consistent with the SDK. The remaining SDK profile log is pre-existing, so no new merge-blocking risk is established.

Filter the Kinde SDK logger before authenticated requests.

kinde_oauth.get_user_info() still logs the complete user-info response at INFO, including profile fields such as email. The PR removes application-level sensitive logs but leaves this SDK log, so the safer-logging change remains incomplete. Configure the Kinde SDK logger itself at WARNING or higher.

This SDK behavior predates the PR; the change reduces duplicate exposure but does not remove the remaining SDK log.
