This module provides two-factor authentication for Drupal users using the Time-based One-time Password Algorithm. It allows users to authenticate with authenticator apps like Google Authenticator, Authy, and Duo Mobile.
One Time Password is an opinionated, lightweight, near zero-configuration module with 100% test coverage. It provides two factor authentication to users by way of the Time-based One-time Password Algorithm (RFC 6238).
The 8.x-1.x branch has no configuration options. The 2.x series have a configuration form with one option - Force users to setup TFA. At some point the configuration option might be removed and that option will be controlled by the branch.
Many apps implement this spec, providing users lots of options for storing and managing their one-time-passwords. Some popular apps which will integrate with this module are:
- Google authenticator (iTunes & Google Play)
- Authy
- Authenticator (Windows phone)
- Duo Mobile
