## OAuthProvider.credential() method
Creates a [OAuthCredential](./auth.oauthcredential.md) from a generic OAuth provider's access token or ID token.
Signature:
```typescript
credential(params: OAuthCredentialOptions): OAuthCredential;
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| params | [OAuthCredentialOptions](./auth.oauthcredentialoptions.md) | Either the options object containing the ID token, access token and raw nonce or the ID token string. |
Returns:
[OAuthCredential](./auth.oauthcredential.md)

// Initialize a generate OAuth provider with a `google.com` providerId.
const provider = new OAuthProvider('google.com');
const credential = provider.credential({
idToken: googleUser.getAuthResponse().id_token,
});
const result = await signInWithCredential(credential);
```
