# createPkpSessionSigs

# Function

> **createPkpSessionSigs**(`params`)

Issues fresh session signatures for a PKP based on pre-generated delegation materials. Pair this with `createPkpAuthContextFromPreGenerated` when a backend needs to sign or execute Lit Actions on demand.

## Parameters

<ParamField path="params.authContext" type="AuthContext" required>
  Auth context obtained from `createPkpAuthContextFromPreGenerated` or `createPkpAuthContext`.
</ParamField>

<ParamField path="params.litClient" type="LitClient" required>
  Lit client that will request session signatures from the network.
</ParamField>

<ParamField path="params.product" type="'DECRYPTION' | 'SIGN' | 'LIT_ACTION' | 'SIGN_SESSION_KEY'">
  Optional override for the product type when you need signatures for a specific capability. Defaults to `LIT_ACTION`.
</ParamField>

## Returns

<ResponseField name="sessionSigs" type="SessionSigsMap">
  Session signatures scoped to the delegated resources.
</ResponseField>

## Example

```ts theme={null}
import {
  createPkpAuthContextFromPreGenerated,
  createPkpSessionSigs,
} from '@lit-protocol/auth';

const authContext = await createPkpAuthContextFromPreGenerated({
  pkpPublicKey,
  sessionKeyPair,
  delegationAuthSig,
});

const pkpSessionSigs = await createPkpSessionSigs({
  authContext,
  litClient,
});
```
