## TwitterAuthProvider class
Provider for generating an [OAuthCredential](./auth.oauthcredential.md) for [ProviderId.TWITTER](./auth.providerid.twitter.md).

```typescript
export declare class TwitterAuthProvider extends BaseOAuthProvider
```
Extends: BaseOAuthProvider
## Example 1
```javascript
// Sign in using a redirect.
const provider = new TwitterAuthProvider();
// Start a sign in process for an unauthenticated user.
await signInWithRedirect(auth, provider);
// This will trigger a full page redirect away from your app
// After returning from the redirect when your app initializes you can obtain the result
const result = await getRedirectResult(auth);
if (result) {
// This is the signed-in user
const user = result.user;
// This gives you a Twitter Access Token and Secret.
const credential = provider.credentialFromResult(auth, result);
const token = credential.accessToken;
const secret = credential.secret;
}
```
## Example 2
```javascript
// Sign in using a popup.
const provider = new TwitterAuthProvider();
const result = await signInWithPopup(auth, provider);
// The signed-in user info.
const user = result.user;
// This gives you a Twitter Access Token and Secret.
const credential = provider.credentialFromResult(auth, result);
const token = credential.accessToken;
const secret = credential.secret;
