# PasskeyProvider

> **PasskeyProvider** = `object`

Defined in: [packages/wallets/src/signers/types.ts:159](https://github.com/Crossmint/crossmint-sdk/blob/main/packages/wallets/src/signers/types.ts#L159)

Creates passkeys and signs with them where the browser WebAuthn API is not available (e.g. React Native).
Passed as the `passkeyProvider` wallet option, it is used for every passkey signer that has no
`onCreatePasskey` / `onSignWithPasskey` of its own.

## Properties

Defined in: [packages/wallets/src/signers/types.ts:162](https://github.com/Crossmint/crossmint-sdk/blob/main/packages/wallets/src/signers/types.ts#L162)

| `credentialId`? | `string` |

#### Returns

`Promise`\<[`PasskeySignResult`](./PasskeySignResult)>
