Why is my 139 mailbox often logged in by others? Is it unsafe? I have changed my password several times.

Hello! Dear, please rest assured that 139 mailbox attaches great importance to the security of user information. Do parents often receive login notification messages for no reason? Did you accidentally reveal the password? If you don't log in yourself, it is recommended to reply to "SD" after receiving the notification message to lock the mailbox, and log in to the mailbox in time to change the password, which is highly secure. You should also avoid accessing 139 email information in public places or unsafe websites to ensure the security of account information. In addition, you can log in to the homepage of your mailbox through the computer, and click "self-service inquiry" below to view the "login inquiry" of your mailbox.
