Carnets vs Test Passkeys

Jupyter notebooks are a powerful tool used in education and research. You can write small snippets of Python code and observe the result on screen, combine with paragraphs of text, using Markdown. Carnets provides a complete, stand-alone, implementation of Jupyter notebooks. Everything runs on your device, using the embedded Python interpreter; you do not need an internet connection. You can chose between Jupyter notebooks and the more advance Jupyterlab using Settings. Numpy, Sympy, Matplotlib, Pandas, lxml, bokeh, nbextensions (including ipywidgets) and many other packages are pre-installed. To see the full list of installed packages, type "%pip list" in a code window. You can add more packages using "%pip install packageName", but only if they are pure Python. If you need scipy, seaborn or scikit-learn, please use our other App, "Carnets - Jupyter (with scipy)". You can share your notebooks with other apps and also open notebooks or directories managed by other apps. Partial list of installed packages: astropy, babel, bokeh, cryptography, cvxopt, Fiona, geopandas, geopy, lxml, matplotlib, numpy, openCV, pandas, pillow, pyFFTW, pyproj, rasterio, regex, shapely, sympy, wordcloud.

Test Passkeys is a hands-on sandbox for learning how passkeys and WebAuthn really work: on a real device, against a real server, with nothing hidden behind a diagram. Most explainers stop at the arrows. This app lets you run the ceremonies yourself, change the parameters, and read every field that crosses the wire. PLAYGROUND Create passkeys and authenticate with them, then inspect the whole exchange: * Configure user verification, attestation, authenticator attachment, resident keys, algorithms and hints - then see what the device does with each * Change the relying party ID and watch iOS accept or reject it, and find out why * Switch between standard and conditional request styles * Read the raw challenge, clientDataJSON, authenticator data and signature for every ceremony * Rename, inspect and delete the passkeys you create LEARN Guided lessons on what passkeys are, how the ceremony fits together, why they are phishing resistant and breach proof, and how platform support is evolving - plus curated links into the WebAuthn, FIDO Alliance and Apple references when you want to go deeper. YOUR ACCOUNT Sign in with a passkey or a password, manage the passkeys registered to your account, and lock the app itself behind Face ID, Touch ID or a PIN. Playground passkeys are purely a learning tool - they are never used to authenticate you anywhere, and the passkeys protecting your own account are kept entirely separate. Experiment as freely as you like. Built for developers integrating WebAuthn, and for anyone who wants to see what is actually happening when they tap "Sign in with a passkey". Free. No ads, no tracking.
