UI Explorer Light vs Test Passkeys

When you are developing your app using SwiftUI, it is really time consuming to compare all possible styles of buttons, list etc to choose one fits best. This app help you check all possible options for SwiftUI's views without recompiling. Compare how they look like on iOS, iPadOS, watchOS, tvOS and MacOS. This version of the app is for checking how iPad's apps look like on ARM Macs.

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.
