AuthMonster

Mobile two-factor authentication with token backup

AuthMonster is a mobile authenticator app for managing two-factor-authentication tokens. It generates short-lived six-digit codes for protected online accounts, providing a second sign-in factor in addition to a password.

Accounts can be added by scanning a setup QR code or by entering the service details and secret key manually. After setup, codes are generated directly on the device and change every 30 seconds, so they can be used when the phone has no internet connection.

The app also includes token categories, pinning, and encrypted local or cloud backups. AuthMonster is positioned for individual users as well as families and small teams, with downloads available for iOS and Android.

Features

QR-code and manual token setup

Add an account by scanning the QR code provided during a service's two-factor-authentication setup, or enter the service details and secret key manually.

Time-based authentication codes

Each token produces a six-digit one-time code that refreshes every 30 seconds and is intended for a single use during sign-in.

Offline code generation

Once a token is added, codes are generated on the device and remain available without an internet or cellular connection.

Local and cloud backup

Save encrypted token backups locally on the device or to the cloud, with an optional password for additional protection.

Token organization

Assign tokens to categories including Work, Personal, Money, Social, Email, Health, and Crypto, and pin important entries for faster access.

Input validation

The app validates scanned or entered information before creating a token and alerts users when an input is invalid or belongs to a different recognized flow.

Use cases

  • Protecting personal online accounts

    Use AuthMonster as the second factor for email, financial, social, work, or other online accounts that support authenticator-app codes. Scan the service's setup QR code and enter the generated code after the account password.

  • Managing family account access

    Keep tokens for different household members or account groups organized with categories and pinned entries. Encrypted backups can help preserve access when a phone is replaced or restored.

  • Organizing accounts for small teams

    Store work-related tokens separately from personal entries and retrieve codes quickly through categories and pinning. AuthMonster's positioning includes small teams, though the source does not describe shared administration features.

  • Signing in while offline

    Continue signing in while traveling or working in locations with unreliable connectivity. Previously added tokens generate codes locally without Wi-Fi or cellular service.

  • Setting up accounts without a QR code

    Use manual setup when a service does not provide a usable QR-code scan, entering its secret key and account details to create the same type of six-digit token.
