The “Try It” feature is disabled for this endpoint because it requires cryptographic WebAuthn authenticator response data that can only be generated during a browser WebAuthn ceremony. Use the Integration Guide for implementation examples.
Finds and retrieves a passkey account by submitting a WebAuthn authenticator response. Useful for account recovery flows and cross-device login where you have the authenticator credential but not the on-chain address.

​
Use Cases

  • Account Recovery: User forgot which account they used but has the passkey
  • Cross-Device Login: User switches devices with synced passkeys
  • Multi-Passkey Management: Select which passkey/account to use

​
Implementation Flow

1

Initiate Get Ceremony

User triggers WebAuthn get() with appropriate challenge
2

Retrieve Credential

Browser/device returns authenticator response
3

Submit to Find

POST authenticator response to /passkeys/find
4

Use Account

Continue with account operations using returned address and session key
This endpoint only finds existing accounts—it doesn’t create new ones. The response includes a fresh session key regardless of existing session status.
