Recently, why does Post Bar always send short messages to log in, for a dime at a time?

X is because login protection is turned on. Just set login protection to recommended.

After entering the post bar, click the small circle next to the account and click account settings.

Enter the account security center, click the secret protection tool, log in for protection, and click Open.

Set login protection, select the first recommended one, and the login window of mobile phone verification code will not be played every time you log in.
