I am trying to find a way that I can integrate identity into my Forms app to look native but still be hassle free. I tried using IdentityServer4 but I'm not keen on looking after passwords and there was a lot of work involved which for one developer isn't great. So I am now looking into Azure AD B2C however I now have to go to a browser to login and I can't make the UI look native. How would I create a login experience such as the one of Facebook where it is all natively in the app using Login Providers such as Facebook, Microsoft, etc... (I understand login providers wouldn't be native, however I would want the buttons to be native) but I don't want to look after passwords. I am using ASP.Net Core as the backend api so what ever I use I need it to work with that.
Any suggestions?
