    What is a passkey and why should you care?

    What is a passkey and why should you care?

    The FIDO Alliance isn't a fan club for dogs, but a consortium of big tech companies that's trying to make authentication more secure. The Alliance has a lofty goal: To kill the password and replace it with something better. Enter the passkey.
    You've probably read a blog post or two about it, but you may be wondering what the fuss is all about. We invited two of the foremost experts on the topic to join us on Android Bytes and explain how passkeys work and why we're better off without passwords.
    Christiaan Brand is a Product Manager on Identity and Security at Google and Tim Cappalli is an Identity Standards Architect at Microsoft.

What is the meaning of "passkey"?21:57 - At a high level, how do passkeys actually work?24:47 - What makes passkeys more resilient to phishing and data breaches?25:52 - How are passkeys backed up?27:15 - What happens if you forget that you made a passkey for a certain site?28:01 - Can you reuse passkeys?28:51 - Can passkeys be exported or transferred between password managers (passkey managers?)?31:44 - How do you use a passkey stored on your phone to login to a website on your PC (or vice versa)?35:50 - Is there a fallback method to support legacy devices?

    The hidden challenges in porting AOSP

    It's dangerous to go alone! Take us with you!
    In this episode, we're joined by our very own Jon West and Nikhil Punathil at Esper to discuss a key part of what we do here — getting AOSP up and running on ARM and x86 hardware. If you want to port AOSP, it's not as easy as just compiling an image from Google's git repos and slapping it onto a device.
    05:59 - What is a device bring-up? What are some of the challenges in doing a bring-up?10:58 - How do AOSP developers deal with a lack of kernel source code?18:16 - How did Project Treble affect building AOSP?26:54 - How does Android on x86 differ from Android on ARM?29:48 - What problem does the Generic Kernel Image try to solve?35:22 - How long does Google support a particular AOSP release? What can AOSP developers do once support has ended?

    The hidden costs of building an Android phone

    The hidden costs of building an Android phone

    As a manufacturer, building an Android phone to the spec you want has its challenges and costs. You need to deal with dozens of regulatory agencies and standards bodies as well as (shudder) work with carriers if you want a chance at making a splash with a new product.
    From assembly to testing to retail, OSOM Privacy is chugging along as it prepares to launch its first smartphone, and we're glad to have co-founder/CEO Jason Keats and chief product officer Gary Anderson join us again for a special, extended, freewheeling episode of Android Bytes.
