An image forming apparatus operable by an operation device includes a storage that stores a plurality of operations, a detector that detects an operation, and a controller. The controller registers a terminal as the operation device if an operation detected by the detector conforms with an operation stored in the storage.

A communication device may: send a change instruction including identification information to a server, wherein the server may store the identification information and target user information corresponding to a user of a terminal device in association with each other, and the change instruction may be a signal to instruct the server to send first authentication information to the terminal device by using the target user information, after the first authentication information has been sent from the server to the terminal device, accept input of the first authentication information, in a case where the input of the first authentication information is accepted, send the first authentication information to the server, in a case where the first authentication information is sent to the server, receive a change permission notification from the server, and in a case where the change permission notification is received from the server, change the password.

A communication device, in a case where a changing request is inputted by a specific user under a situation where a memory stores a first password used by a plurality of users, send first information to each of a plurality of destinations, the changing request being for changing the first password to another password; and in a case where the first information is used in a first destination among the plurality of destinations and an instruction for changing the first password to the another password according to the changing request is provided by a first user after the first information has been sent to each of the plurality of destinations, store a second password in the memory instead of the first password.

An information processing system includes an image processing apparatus including first circuitry and an information processing apparatus including second circuitry The first circuitry of the image processing apparatus reads an application form with a scanner to generate image data, acquires electronic watermark data from the image data, acquires, from an integrated circuit card, first identification information of the integrated circuit card, and creates application data based on the application form. The second circuitry of the information processing apparatus communicates with the image processing apparatus via a network, and performs user authentication based on the first identification information of the integrated circuit card acquired from the integrated circuit card and second identification information of the integrated circuit card previously associated with identification information of the application form. The first circuitry of the image processing apparatus stops creating the application data when the user authentication fails.

An image forming apparatus that executes a password-protected job includes a function for omitting an input of a job password, manages a user password for keyboard authentication in association with a user, manages a personal identification number for icon authentication in association with the user, accepts login to an account of the user based on the keyboard authentication, permits execution of a password-protected print job associated with the user based on a print instruction without inputting a job password, accepts login to the account of the user based on the icon authentication, and permits execution of a password-protected print job associated with the user based on a print instruction with an input of a job password.

A system includes an image processing apparatus and an information processing apparatus that provides a chat service, the image processing apparatus includes a reading unit that reads an image on a document, a memory, and a processor that executes a program stored in the memory to generate a file based on the read image, receive a password from a user, encrypt the generated file, using the received password, and transmit the encrypted file and the received password to the information processing apparatus, wherein the information processing apparatus includes a memory, and a processor that executes a program stored in the memory to cause the information processing apparatus to receive, from the image processing apparatus, the encrypted file and the received password, execute processing for posting the received encrypted file to a channel specified by the user, and execute processing for posting the received password to the channel.

According to an embodiment, it is possible to restrict usage of a web-based service error resolution service by multifunctional peripheral devices or the like. A multifunction device for such purposes includes a display unit with a display screen, a device unit configured to generate an error code when an error in the device unit occurs, and a processor. The processor configured to acquire the error code from the device unit and transmit an error notification including the error code to an external apparatus. The processor then receives a counted number of errors from the external apparatus, and then select an error resolution screen to be displayed on the display screen based on the received counted number of errors.

A method, a non-transitory computer readable medium, and multifunction printer are disclosed for injecting screens into a third-party workflow on a display panel of a multifunction printer. The method includes displaying, on the display panel of the multifunction printer, a first screen from a third-party workflow; detecting, on the multifunction printer, a first authentication attempt from a user; inserting, on the display panel of the multifunction printer, a first screen from an authentication workflow into the third-party workflow upon the detection of the first authentication attempt from the user; sending, from the multifunction printer, authentication data associated with the first authentication attempt to an authentication server; receiving, from the authentication server, an authentication result associated with the first authentication attempt; and displaying, on the display panel of the multifunction printer, a second screen from the third-party workflow following a successful authentication result from the authentication server.

An image forming apparatus includes a communication interface, a processor, and a memory. The communication interface communicates with an external service including an authorization code flow. The memory stores a front-end application having a UI and a back-end application having no UI and registered in the external service, which are programs executed by the processor. The processor causes the external service to execute the authorization code flow based on the information of the back-end application in response to a request from the front-end application, receives an authorization code from the external service, causes the front-end application to redirect using a URL previously associated with the back-end application on the external service, and acquires an access token from the external service by the back-end application using the authorization code.

An image processing apparatus transmits a request to a content server at a specific timing such as login, logout, auto-clear, print start. The image processing apparatus receives contents provided from the content server in response to the request, and displays the contents in an operation unit. If a user operating the image processing apparatus is specified by user authentication, the image processing apparatus adds information of the user to the request, and receives the content modified by the content server according to the information of the user from the content server and displays the modified contents.
