Some time ago, every time I knew in Baidu that I had to bind my mobile phone to ask questions, I sent a message when I got the answer. Should I deduct the phone bill or the SMS fee?

Baidu mobile phone is free, and there is no charge for SMS.

Because the phenomenon of number hacking in Baidu is more serious now, Baidu requires users to bind their mobile phones or mailboxes, also for the safety of users' accounts.

Bind the mobile phone, and if you don't want to receive the answer, you can set not to accept the Baidu SMS reminder answer.

Setting method:

After logging in to Baidu, click "My Know" in the upper right corner, then click "My Settings" in the lower left corner, and then in the "Contact Information" of "Personal Information", just remove the box in front of "Set Reminder Message".

Now Baidu can unbind. The unbinding method is:

After logging in to Baidu, hover your mouse over your name "Slag Head" in the upper right corner, then click "Account Settings", then click "Modify Authentication Mobile Phone", and then click "Secret Security Tool" to unbind or modify your authentication mobile phone.

When you click "Unbind", Baidu system will remind you:

Note: Unbinding the mobile phone will greatly reduce the security of the account.

We strongly recommend that you modify the bound mobile phone.

Because Baidu hackers often occur, in order to protect the security of user accounts, Baidu hopes that users can bind their mobile phones and mailboxes.

At the same time, try to make the password setting more complicated.
