Context-based authentication of a user

A method for authenticating a user, comprising:

• receiving, by a device and based on receipt of a session input, a notification to authenticate a user associated with a user account of an application server,
• wherein the session input includes a set of variables that correspond to a set of parameters of an operation of the application server, and
• wherein the notification includes an account identifier of the user account and the set of parameters of the operation;
• identifying, by the device and based on the account identifier, a plurality of user devices that are associated with the user;
• selecting, by the device and based on a type of the operation, a user device from the plurality of user devices to be used to authenticate the user;
• sending, by the device and to the user device, an authentication request that prompts the user to provide a contextual description that describes the set of parameters of the operation;
• receiving, by the device and from the user device, an authentication response that includes the contextual description;
• determining, by the device, a context-based authentication score based on a quantity of characteristics, of a set of described characteristics, within the contextual description, that are determined to be associated with the set of parameters of the operation;
• and
• causing, by the device and based on a the context-based authentication score satisfying an authentication threshold score, performance of the operation based on the parameter of the operation.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a system, cause the system to:
• receive, based on receipt of a session input, a notification to authenticate a user associated with a user account of an application server,
• wherein the session input includes a set of variables that correspond to a set of parameters of an operation of the application server, and
• wherein the notification includes an account identifier of the user account and the set of parameters of the operation;
• send, based on receiving the notification, an authentication request to a user device associated with the user,
• wherein the authentication request includes a message indicating that the user is to provide a contextual description that describes the set of parameters of the operation;
• receive, from the user device, an authentication response that includes the contextual description;
• authenticate the user based on a context-based authentication score satisfying an authentication threshold score,
• wherein the context-based authentication score is determined based on quantity of characteristics, of a set of described characteristics, within the contextual description, that are associated with the set of parameters of the operation;
• and
• cause, based on authenticating the user, performance of the operation.
