Migration Guide:
If you were manually providing a config when instantiating an Api object change your config code to:
from n26.api import Api
from n26.config import Config
conf = Config(validate=False)
conf.USERNAME.value = "john.doe@example.com"
conf.PASSWORD.value = "$upersecret"
conf.LOGIN_DATA_STORE_PATH.value = None
conf.MFA_TYPE.value = "app"
conf.validate()
client = Api(conf)
