# createPkpAuthContextFromPreGenerated

# Function

> **createPkpAuthContextFromPreGenerated**(`params`)

Rehydrates a PKP auth context from pre-generated session materials. Ideal for server or lambda environments that receive `{ sessionKeyPair, delegationAuthSig }` and want to issue fresh session signatures on demand.

## Parameters

<ParamField path="params.pkpPublicKey" type="string" required />

<ParamField path="params.sessionKeyPair" type="SessionKeyPair" required />

<ParamField path="params.delegationAuthSig" type="AuthSig" required />

<ParamField path="params.authData" type="AuthData">
  Optional override when you need to supply explicit auth data instead of relying on the delegation contents.
</ParamField>

## Returns

<ResponseField name="authContext" type="AuthContext">
  Auth context compatible with `litClient.executeJs`, `pkpSign`, or further session signature issuance.
</ResponseField>

## Example

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

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