Questions, what account types are possible besides a homebrew for the application and Windows (thinking the user has only one account at a time even though they may have several e.g. a PA account and regular account). Then how were you think about defaulting to “Use this account”.
Thinking you have done research which lead to asking this question I would recommend a hybrid solution which would not have “Use this account” but other for instance sign in with user name/password or say email address and password etc.
You can check out How to prompt for a password on Windows? which requires access to the web and a free NuGet package.
