Passkey Wallet

A wallet that authorises transactions using a device passkey — face, fingerprint or PIN — instead of a written seed phrase.

✦ Key Insight

It removes the most common cause of retail loss — mishandled seed phrases — while introducing dependence on the platform account that syncs the passkey.

✕ Common Misconceptions

Assuming there is nothing left to secure. Your platform account now controls wallet access, so it needs strong authentication of its own. Check whether the wallet offers an export path before committing significant funds.

Detailed Explanation

Passkey wallets use the same standard that replaces passwords on phones and laptops. The signing key is held in the device's secure hardware and synced through the platform's account system. This removes the seed phrase from the user experience, and moves the recovery question to your device ecosystem account.

In Practice

“A new user sets up a wallet with Face ID, makes a swap without ever seeing a word list, and recovers on a replacement phone via their platform account.”
