## setPersistence() function

Changes the type of persistence on the Auth instance for the currently saved Auth session and applies this type of persistence for future sign-in requests, including sign-in with redirect requests.

<b>Signature:</b>

```typescript
export declare function setPersistence(auth: Auth, persistence: Persistence): Promise<void>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  auth | [Auth](./auth.auth.md) | The Auth instance. |
|  persistence | [Persistence](./auth.persistence.md) | The [Persistence](./auth.persistence.md) to use. |

<b>Returns:</b>

Promise&lt;void&gt;

A promise that resolves once the persistence change has completed

## Remarks

This makes it easy for a user signing in to specify whether their session should be remembered or not. It also makes it easier to never persist the Auth state for applications that are shared by other users or have sensitive data.

## Example


```javascript
setPersistence(auth, browserSessionPersistence);

```
