Overview
What the SplitSecure Passkey Browser Extension is and how it works
What is the Passkey Browser Extension?
The SplitSecure Passkey Browser Extension lets you create and sign in with passkeys on websites, directly from Chrome. The keys stay protected by SplitSecure.
How It Works
When a website asks you to register or sign in with a passkey, the extension picks up that request, completes it through SplitSecure, and returns the result to the site. The passkey’s private key is never exposed. Its key material is recombined inside the trusted computing base only after your approval set approves the request, then deleted immediately after use.
The extension stays inactive until you open it, so it doesn’t interfere with other passkey providers on your machine. Because of this, the extension has to be open at the moment a site prompts you for a passkey.
Open the extension before you create a passkey or sign in. While it’s closed, it won’t respond to a site’s passkey prompt.
