Note: If it is a secret security problem or a secret security mobile phone, mobile qq cannot be set. If you want to set or modify it, you need to log in to qq with a computer and set it in the security center.

Extended data:

In fact, whether the password is stolen or forgotten, a simple and practical method is to apply for QQ password protection. Click the link above, enter the QQ account number, QQ password and verification characters, and fill in all the information according to the prompts (note, be sure to remember the information you have filled in, and remember the information you need to retrieve the password in the future, especially the ID number.

Some mailboxes cannot receive QQ mail, so it is recommended to use QQ mailbox). Password protection can ensure that your QQ number is more secure, and help you find your new password more conveniently and quickly when there is a problem with your password. However, at present, the newly applied numbers generally need to fill in the second-generation password to protect the data, so the general 9-digit numbers are protected by the second-generation password and do not need to be applied separately.
