Their device was expensive, somewhat clunky due to the technology of the day, proprietary, patented up to the eyeballs, and finally orphaned in a dysfunctional venture capital disaster. But the patents have long expired, and Vik wrote the original PC keyboard drivers...\r\n\r\nQuirkey re-implements the system Microwriter painstakingly developed. It's now a palm-sized, driverless HID keyboard device made using 3D printing and off the shelf Open Source hardware. The result is cheap, customizable, Open in every way, and thanks to all the above, easy to make in any modest Maker Space. This presentation covers creating a custom parametric 3D printed shell in OpenSCAD, and making firmware that runs on more or less any Arduino/Pico/ESP32 with USB or Bluetooth HID.

Learn how\r\nFreeIPA and SSSD have grown support for FIDO2 passkeys and for\r\nauthenticating users from external OAuth 2.0 identity providers.\r\nThere will be demos!\r\n\r\nAuthentication is a critical aspect of host, network and\r\norganisational security. Identity management systems like FreeIPA\r\ncentralise your identities and access policies, to help you meet\r\nyour security and compliance requirements.\r\n\r\nHistorically and up to the present day, passwords were widely used\r\nfor initial user authentication. But in the current era a healthy\r\nsecurity posture often demands 2FA, hardware cryptographic tokens,\r\nconsumption of identity assertions from third party providers, or\r\nsome combination of these. Major trends in the web authentication\r\nlandscape include *Passkeys*, and delegation of authentication to\r\nthird-parties (sometimes called \"Web SSO\").\r\n\r\n*Passkeys* is a convenient, passwordless, phishing-resistant\r\nauthentication technology based on FIDO Alliance standards. It uses\r\npublic key cryptography and the credential can be implemented in\r\nsoftware or hardware.\r\n\r\n*OAuth 2.0* is an access delegation protocol widely used on the web.\r\nYou have probably seen services that offer \"Log in with {popular\r\nsite}\". When you use these options, OAuth 2.0 (or the OpenID\r\nConnect protocol which builds upon it) are what happens behind the\r\nscenes. OAuth 2.0 also support non-web applications via the *Device\r\nauthorisation grant* flow.\r\n\r\nRecent releases of FreeIPA and its client-side companion SSSD added\r\nsupport for both of these authentication technologies. In this\r\npresentation I will review how these mechanisms work, and describe\r\nwhat had to be added or changed in FreeIPA and SSSD to support them.\r\nAttendees will learn, via practical demonstrations, how to configure\r\ntheir own systems and networks to use these modern, secure\r\nauthentication mechanisms.", "conf_url": "https://2024.everythingopen.au/schedule/presentation/19/", "cancelled": false, "twitter_id": "hackuador", "mastodon_id": "@hackuador@functional.cafe" }, { "room": "Echidna (Gegair)", "rooms": [ "Echidna (Gegair)" ], "start": "2024-04-18T13:30:00", "end": "2024-04-18T14:15:00", "duration": 45, "kind": "talk", "section": "main", "section_name": "Main Conference", "track": null, "conf_key": 41, "license": "CC-BY-SA", "tags": "", "released": true, "contact": [], "name": "Spellcasting at home - voice assistants without the cloud", "authors": [ { "name": "Christopher Biggs", "name_pronunciation": "", "pronouns": "he/him", "twitter": "unixbigot", "mastodon": "unixbigot@aus.social", "contact": "redacted", "picture_url": "/site_media/media/speaker_photos/iot-avatar-400.jpeg.120x120_q85_crop.jpg", "code": "56", "biography": "Christopher Biggs has been into Open Systems since the early 90s and was there at the birth of Linux and 386BSD.
