Abstract
Techniques involve a user taking a picture of a current one-time use passcode (OTP) and using the picture to authenticate. Such techniques alleviate the burden and frustration of the user having to manually type in the current OTP. Additionally, the user will not trigger a lockout via accidental typing errors. Furthermore, the current OTP can be augmented to include more than a string of six or eight alphanumeric characters for stronger security (e.g., by using non-alphanumeric characters, by capturing multi-digit seven-segment LCD display patterns, by using a QR code, by using a randomly selected image, etc.). One technique involves taking a picture of an OTP provided by a user. The particular technique further involves extracting the OTP from the picture and performing an authentication operation based on the OTP extracted from the picture to determine whether the user is authentic.
