# How to Access Duo Multi-Factor Authentication

#### **What is Duo?**

Two-Factor Authentication (MFA) adds a second layer of security to your SJSUOne account. By verifying your identity using a second factor (such as your mobile device or a key fob), MFA prevents anyone else from logging into your account, even if they know your password

#### **Who should use Duo?**

Students should set up Duo MFA to protect their account and private information from being hacked. As of September 2020, it is available to all SJSU staff and students

#### **How does Duo work?**

Two-Factor Authentication combines something you know (your username and password) with something you carry (your Apple or Android smartphone, or a Hardware Token / Key-Fob), to ensure that only you can log in to your SJSUOne account. After entering your username and password you will be prompted to confirm your login, using your device

##### Cost

- Using the smartphone app factor is covered by the CSU master license
- Hardware tokens (key fobs) are purchased by SJSU and provided to you. Replacements are available for broken or lost fobs

The current procedures for student access to Duo are only for smart phones, so please contact the [IT Service Desk](http://www.sjsu.edu/it/support/service-desk/index.php) for assistance by calling 408-924-1530 or by submitting a [help desk ticket](https://www.sjsu.edu/it/support/service-desk/help-ticket.php). Because Duo MFA is a security service, the IT Service Desk must confirm your identity before providing assistance.
