Two Factor Authentication

QRZ now offers enhanced login security for its members.  By using this option, you can protect your QRZ account from access by unauthorized individuals.

Two Factor Authentication means that that two pieces of information, in addition to your user name, are required to complete the login process.  One of those pieces of information is your QRZ password and the other is a time limited secret code, called a token, that is either generated by an App on your device, or is sent to you via text message.  Once you have enabled 2FA, your password, even if accidentally shared or disclosed to others, will not compromise your account because your second factor (the token code) cannot be stolen. QRZ recommends this facility for all of its users.

Two Factor authentication is currently not enabled on your account.
