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.
