From what I noticed, the authData.providerData is an array of length 0 and hence \n`providerId = authData.providerData[0].providerId;`\n\nresults in undefined error.\n\nI do not know where the fix should be -\n\na) Should Firebase return providerData \u0026 providerId set to \"custom\" as expected by AngularFire2 ?\n\nor\n\nb) Should AngularFire2 determines that authentication used was custom so there will be no providerData ?\n\nRegards\nKapil\n","author":{"url":"https://github.com/ksachdeva","@type":"Person","name":"ksachdeva"},"datePublished":"2016-06-27T12:50:09.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/292/angularfire/issues/292"}
