The present disclosure provides an information output method and a device. The method comprises the steps of upon receiving the directional information sent by a terminal device corresponding to a first account number, sending a new message notification to a terminal device corresponding to a second account number in group relationship with the first account number, wherein the new message notification is used for prompting the occurrence of the new directional information in the group; receiving the authentication information sent by the terminal device corresponding to a second account number; on the condition that the access right of the directional information needs to be opened to the second account number based on the authentication information, sending an information output instruction to the terminal device corresponding to the second account number, wherein the information output instruction is used for indicating the terminal device corresponding to the second account number to output the directional information. In this way, according to the technical scheme of the invention, when one user in a group edits a piece of information and sends the information to a group chat, other users in the group can only see the content of the information after passing the authentication operation through inputting the authentication information. Therefore, the requirement that only one part of users in the group chat can see the information can be met.
