• at least one processor executing the instructions to perform operations for authenticating a source of a telephone call to a recipient of the telephone call, the operations including:
• receiving, prior to receiving the telephone call, a request to input first authentication information,
• wherein the first authentication information comprises a passcode or a selection of a security question;
• receiving input of the first authentication information;
• sending the first authentication information to a computing device associated with the source of the telephone call;
• receiving the telephone call from the source;
• receiving input from the recipient of the telephone call to answer the telephone call;
• receiving second authentication information from the computing device,
• wherein the second authentication information comprises the passcode or an answer to the security question;
• and
• outputting, by the user device, the second authentication information.

• receiving, prior to receiving the telephone call, a request to input first authentication information,
• wherein the first authentication information comprises a passcode or a selection of a security question;
• receiving input of the first authentication information;
• sending the first authentication information to a computing device associated with the source of the telephone call;
• receiving the telephone call from the source;
• receiving input from the recipient of the telephone call to answer the telephone call;
