adding it via configuration.yaml with:

kia_uvo:
    username: !secret kia_user
    password: !secret kia_password

results in a checking error:

Invalid config for [kia_uvo]: [username] is an invalid option for [kia_uvo]. Check: kia_uvo->kia_uvo->username. (See /config/configuration.yaml, line 27).
