## AuthError.tenantid property

The tenant ID being used for sign-in/linking.

<b>Signature:</b>

```typescript
readonly tenantid?: string;
```

## Remarks

If you use [signInWithRedirect()](./auth.signinwithredirect.md) to sign in, you have to set the tenant ID on [Auth](./auth.auth.md) instance again as the tenant ID is not persisted after redirection.
