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?
誰かがあなたのアカウントにログインをしようと試みたので通知が行われました. 以前から使用していないデバイスやブラウザでログインしようとしたとき、ログインに失敗すると最初から通知が行われます. 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?
あなたのアカウントは複雑なパスワードが設定されているべきです. もし、複雑なパスワードではないなら、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、1,000万人のインターネット利用者のうち、約17%がパスワードに"123456"を使っ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!

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.

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.

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 notifications are on for everyone and email ones are turned off. 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 off by default. Note that the web notifications are disabled for this feature. The email text says "" You can enable this in your preferences.
