Important:
The feature to enable multi-factor authentication (MFA) for Home Assistant Cloud is currently not available. If you already have MFA working, MFA will continue to work. But once you disable MFA, you won't be able to enable it again right now.
About multi-factor authentication
Multi-factor authentication uses a combination of two or three different ways to authenticate your identity:
- Something you know (like a password)
- Something you have (like a code generated by a device or service only you have access to)
- Who you are (indicated by some biometric such as a fingerprint)
If you enable multi-factor authentication for Home Assistant Cloud, in addition to your password, you will be asked for a code from a multi-factor authentication application such as Google Authenticator.
