for websites and services that really care about securing data, dual authentication can be the most powerful tool for ordinary users to block unauthorized users from accessing their data. In this way, even if someone has your password, they have to access the device in your hand, such as a cell phone, to change the password. Typically, the dual authentication system sends you an email or text message, or calls you to enter the resulting code to modify the password.
Here's how to turn on dual a
I am using a sniffer tool called Dnsquerysniffer, which can display real-time DNS query records for local computers, and for each DNS resolution query, display the following information: Host name, port number, query ID, request type, request response time, response code, etc. and returns the contents of the DNS record. Domain name added to the Hosts file, Dnsquerysniffer will no longer detect the domain name parsing, and then continue to run sniffer sniffer and application software, one to find
