Why does my account show that the user is not logged in?

Because it is not sealed for a long time, you will be prompted that the account is not protected for a long time and needs to be unsealed first. Enter the account unsealing interface, enter the mobile phone number that can accept SMS now, enter the verification code, and click Next. At this time, you will be prompted to send a short message with specific content. Click "Send SMS now" and the phone will automatically edit the SMS for you. If the SMS is sent successfully, return to the original interface and click "I have sent SMS, next message", which will remind you that you can log in to your account!
