你好！你来到此页面的原因是你收到了关于你的账户登陆通知吗？无需担心，你的账户现在仍然安全.

为什么我会收到这个通知？
你收到通知缘故是有人尝试（但未成功）登陆你的账户. 如果你在先前未曾使用过的设备或浏览器上进行登陆尝试，在首次登陆尝试失败后，你将收到此通知. 如果是在已知设备或浏览器上进行，在五次尝试失败后将触发此通知.

通知是2017年推出的功能之一，由 LoginNotify生成,

我应该做什么?
你应该 为你的账户创建一个强大且独特的密码， have a strong and unique password. 如果你认为这无关密码强度，你应该尽快修改密码，change your password. 根据一项泄露密码的研究显示，在千万的互联网用户账号中，有将近17%的密码为“123456”. 请不要成为其中之一！ Even if you do have a strong password, you may want to change passwords anyway, if you suspect that someone else has tried to access your account.

此外，最好将电子邮件地址关联到你的账户，当你无法访问你的账户并希望重新登陆时将起作用. 你可以在你的设置中设置电子邮件 Preferences page. 或许你也想浏览 this essay on how to prevent account hijacking，其中有一些你在使用互联网时应牢记的常用技巧.

这个功能是如何工作的?
The extension keeps track of known devices (browsers really) by placing a cookie in the browser. This cookie automatically expires in 180 days. If a failed login attempt happens from a new browser, it generates an Echo notification alerting the user about the login attempt. The other way that we identify known devices is by checking the current IP address subnet against the IP addresses that have been used recently (as stored in a temporary server cache). None of the information is stored in a database and at no point is any private information revealed publicly, including the attacker’s IP address/location. The WMF Legal and Security teams have reviewed the implementation for both compliance with our Privacy Policy and security considerations.

For known devices/IPs, we allow up to 5 login attempts before alerting the user about the login attempt, since it's fairly common to mistype or forget a password. If there are 5 or more failed attempts, the notification will say: "" There would be another notification at 10 attempts, 15 attempts and so on.

For unknown devices/IPs, we alert on every failed attempt. The extension bundles these notifications to avoid spamming users with too many notifications. For example, if there are 3 failed attempts from an unknown device, there will be a single notification, which says: "" On further attempts, that notification would update to say "4 failed attempts", "5 failed attempts", and so on.

Things to note
There are two ways for users to get these notifications – either by web Echo notifications or by email. By default, the web and email notifications are on for everyone. This is configurable in the notification preferences.

Successful logins
The extension allows you to get an email when a user logs in successfully to your account from an unfamiliar device and IP. This is especially helpful for admins or other functionaries who are concerned that their rights might be misused. This notification is on by default. Note that the web notifications are disabled for this feature. The email text says "" You can disable this in your preferences.
