# LiumTwoFactorRequired

```python
from lium.sdk import LiumTwoFactorRequired
```

Defined in `lium.sdk.exceptions`.

```python
LiumTwoFactorRequired(mfa_token: str)
```

## Catching it

`LiumTwoFactorRequired` subclasses [`LiumSessionError`](/developers/sdk/reference/exceptions/lium-session-error) → [`LiumAuthError`](/developers/sdk/reference/exceptions/lium-auth-error) → [`LiumError`](/developers/sdk/reference/exceptions/lium-error) → `Exception`, so a handler for any of those also catches it.

```python
from lium.sdk import LiumTwoFactorRequired

try:
    ...  # any SDK call
except LiumTwoFactorRequired as e:
    print(e)
```
