A technique communicates a password to a user. The technique involves receiving, by processing circuitry, a request for a password. The technique further involves generating, by the processing circuitry, a password in response to the request. The password includes a series of alphanumeric digits which contains at least one number and at least one letter. The technique further involves displaying, by the processing circuitry, the password on a display screen. Each number displayed on the display screen has a first visual characteristic, and each letter displayed on the display screen has a visual characteristic that is different from the first visual characteristic. Such a technique enables disambiguation of an alphanumeric security code to a user.
