one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the computing device to:
train, using training data comprising account records from a plurality of different users, a first machine learning model to output, for a particular device, an indication of device reliability data associated with the particular device, wherein the account records are associated with a plurality of devices used by the plurality of different users to access one or more accounts in the account records;
receive, from a user device, a request for access to an account associated with a user;
receive, from one or more databases, account data corresponding to the account,

receive, from the trained first machine learning model, data indicating device reliability for the set of devices;
determining, based on the device history, one or more false devices that the user has not used to access the account for the predetermined period of time;
generate, based on the data indicating device reliability for the set of devices, a set of modified device choices by excluding one or more devices having corresponding reliability levels below a threshold value, from the set of devices, wherein the set of modified device choices comprise the one or more false devices;
generate an authentication question comprising at least one device choice from the modified set of device choices;
generate, based on the account data and the modified set of device choices, a correct answer to the authentication question;
provide the authentication question to the user device;
