System and method for non-numeric authentication using a legacy telephone

Abstract

A request to authenticate a user is received at an authentication system. The request to authenticate the user requires one or more non-numeric metrics to authenticate the user. For example, the one or more non-numeric metrics may include a user name, a password, and a fingerprint scan. The request to authenticate the user that requires the one or more non-numeric metrics is validated. In response to validating the request to authenticate the user that requires the one or more non-numeric metrics, a first numeric code is generated (e.g., a password). The first numeric code is used to grant access to a telephone that requires authentication via a numeric keypad. The first numeric code is sent and displayed to the user. The user can then access the telephone by providing the numeric code at the telephone.
