Claim 8:
9. An apparatus configured to securely authenticate users conducting transactions during electronic calls, the apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
detect, via a secure transaction application, first user input corresponding to a user interface element that initiates, by the apparatus, a communications session, wherein the communications session is one of: a voice call, or a video call;
receive, via the secure transaction application, from a server, and during the communications session, an authorization request corresponding to a transaction, wherein the authorization request is received via a first communications channel that is different from a second communications channel used for the communications session;
cause display, via a user interface of the secure transaction application, of a request to approve one or more goods or services to be purchased via the transaction;
receive, via the user interface of the secure transaction application, in response to the request, and during the communications session, second user input indicating whether the transaction is authorized;
identify, during the communications session, the user of the computing device by processing, using a trained machine learning model, voice data from the communications session, wherein the trained machine learning model was generated by training, using training data comprising a history of voice samples captured during past calls by a user, a machine learning model to identify the user based on voice samples of the user;
determine, via the secure transaction application, based on the identifying the user, and based on comparing one or more properties of the transaction to a threshold, whether to authenticate a user of the apparatus; and
in response to the second user input and based on determining to authenticate the user of the computing device, transmit, to the server, an authorization of the transaction, wherein the authorization of the transaction is configured to cause the server to initiate payment for the transaction using payment information associated with the user.
