About

QMFA Wallet

Read full description

Qwantum™ Multi-Factor Authentication (QMFA) Wallet acts as a secure repository specifically for saving and managing Qwantum Tokens. It is currently available as an iOS app and Apple Watch app. Displaying its QR Code to a barcode-enabled MagTek MMS Dyna Device, it allows for secure reading and authenticated access into various physical and digital systems. It also eliminates the use of usernames and passwords as knowledge-based authentication data and eliminates Personally Identifiable Information (PII). What kinds of tokens can you store? - Simple text: Store any plain string of data you need to access quickly. - URLs/UIRs: Tokens that, when scanned, open a specific web link. - URLs/URIs with integrated data: Seamlessly access websites and automatically input token data or TOTP codes into the correct fields. What Authentication Methods are Supported? - One-Time Codes (OTC) or multi-use Timed Access Codes (TACs): Receive real-time generated codes via SMS or email. - Time-Based One-Time Passwords (TOTP): Keep your dynamic security codes readily available using the QMFA Wallet app for iOS. Qwantum Security, by MagTek, has unlimited possibilities with a foundation built on securing data, access, and systems.
