True - you can not directly access the password in the Bubble DB. The thing to search for in the forum is “Using Bubble as an Oauth provider” If your .net app can accommodate this approach you are in good shape and happy days. Something like this - Bubble App as Oauth2 Provider - #2 by Jici
Otherwise you can revert to more hacky approaches like capturing the credentials in your .net app and then testing if they authenticate to Bubble (a few ways to do that, login to a Bubble page programmatically, test Oauth authentication to an API endpoint.)
