asp.net mvc - How to login using email in identity 2? -

in mvc5 identity 2 signinmanager.passwordsigninasync take user name login.

var result = await signinmanager.passwordsigninasync(model.email, model.password, model.rememberme, shouldlockout: false); 

but user name , email not same. want email address login.so how can that? thanks

get user usermanager email.

var user = usermanager.findbyemail(email); 

then use signinmanager's passwordsigninasync user's username

var result = await signinmanager .passwordsigninasync(user.username,password,ispersistent,shouldlockout); 

or inside signinmanager add method (asp.net identity discussion)

public async task<signinstatus> passwordemailsigninasync(string email, string password, bool ispersistent, bool shouldlockout) {       var user =  usermanager.findbyemail(email);       return await passwordsigninasync(user.username,password,ispersistent,shouldlockout); } 

then use same passwordsigninasync user email instead of usermane.
