If Modern Authentication is forced, are app passwords still working?

Microsoft announced that with Modern Authentication starting from October 1st 2022 basic authentication will be disabled.

But when reading articles about app passwords, it seems to me that they are still supported.

I also could not find any document saying that app passwords are deprecated with October 1st.

But because app passwords use basic authentication I am not sure whether they will still work or not.

    Once Basic auth is deprecated, app passwords will no longer work, as detailed here: https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online

    The deprecation of basic authentication will also prevent the use of app passwords with apps that don't support two-step verification.
