PassCard

End-to-end encrypted passkey manager for your browser.

PassCard is an end-to-end encrypted Passkey management extension that helps users create, store, and use Passkeys directly in their browser, reducing reliance on traditional passwords. All private keys are generated and encrypted locally within the extension. The master password, decryption keys, and unencrypted private keys are never uploaded to the server. Users can securely synchronize encrypted credentials across devices and must explicitly confirm each time a Passkey is created or used. Install PassCard to manage Passkeys for different websites in one place and enjoy a more convenient, secure, and user-controlled passwordless sign-in experience.
