* you need to store JSON data in the cloud,
1313
* you want to sync that data to other devices and platforms,
14+
* you want to optionally protect that data by having users log in,
1415
* you want to update clients at the moment the data changes (think chat and multiplayer games).

137+
### login
138+
v 1.1.0 of this plugin adds the capability to log your users in. Either anonymously or by email and password.
139+
You need to add support for those features in your Firebase instance at the 'Login & Auth' tab.
140+
141+
You can expect more login mechanisms to be added in the future.
142+
143+
#### Anonymous login
144+
```js
145+
firebase.login({
146+
// note that you need to enable anonymous login in your firebase instance
147+
type: firebase.loginType.ANONYMOUS
148+
}).then(
149+
function (result) {
150+
// the result object has these properties: uid, provider, expiresAtUnixEpochSeconds, profileImageURL, token
151+
JSON.stringify(result);
152+
},
153+
function (errorMessage) {
154+
console.log(errorMessage);
155+
}
156+
)
157+
};
158+
```
159+
160+
#### Password login
161+
```js
162+
firebase.login({
163+
// note that you need to enable email-password login in your firebase instance
164+
type: firebase.loginType.PASSWORD,
165+
email: '[email protected]',
166+
password: 'theirpassword'
167+
}).then(
168+
function (result) {
169+
// the result object has these properties: uid, provider, expiresAtUnixEpochSeconds, profileImageURL, token
170+
JSON.stringify(result);
171+
},
172+
function (errorMessage) {
173+
console.log(errorMessage);
174+
}
175+
)
176+
};
177+
```
178+
179+
### logout
180+
Shouldn't be more complicated than:
181+
182+
```js
183+
firebase.logout();
184+
```
