こんにちは！アカウントへのログインの試行通知が行われたというメッセージからここに来ましたか？安心してください！あなたのアカウントはまだ安全です.

なぜ通知が行われましたか?
他人があなたのアカウントにログインをしようと試みた可能性があるため、通知が行われました. 以前に使用したことのないデバイスやブラウザでログインしようとしたとき、1度ログインに失敗すると通知が行われます. 既知のデバイスやブラウザでログインしようとしたとき、5回ログインに失敗すると通知が行われます.

この通知は2017年に実装されたLoginNotifyの機能により運用を開始しました.

何をしたらよいですか?
アカウントのパスワードを複雑にすることが推奨されます. もし、複雑なパスワードでない場合は、できるだけ早くパスワードを変更してください. ある調査によれば、1千万人のインターネット利用者のうち、約17%がパスワードを"123456"に設定しているという結果が出ています. 彼らだけの問題ではありません! 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.

Also, it might be a good idea to associate an email address with your account in the event you lose access to your account and want to get back in. You can set your email on the first panel of your Preferences page. You might also want to glance through this essay on how to prevent account hijacking, which has some general tips you should keep in mind when using the internet.

How does this feature work?
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.

留意事項
ユーザーがこれらの通知を得るには、ウェブサイトかメールの2つの方法があります. 既定では、ウェブサイトの通知が有効になっていて、メールの通知は無効となっています. これは、個人設定の通知から調整が出来ます.

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.
