angular - Firebase EmailPasswordAuthProvider Does Not Exist on Type Auth -

in angular2 / typescript environment, following code firebase documentation errors "emailpasswordauthprovider not exist on type auth".

var credential = firebase.auth.emailpasswordauthprovider.credential(email, password); 

https://firebase.google.com/docs/auth/web/anonymous-auth convert anonymous account permanent account

have installed latest firebase typings version: firebase@3.0.5

note other firebase methods working okay , auth object requires open/close brackets e.g.

firebase.auth().createuserwithemailandpassword(email, password); 

this bug in typescript definitions. firebase team has been notified , working on fix. in meantime use following workaround:

(<any> firebase.auth.emailauthprovider).credential
