Two-factor (TOTP) authentication

OneTimePass is a clean and robust two-factor TOTP application and supports the following features:

  • Supports opening otpauth:// URLs
  • Scan QR codes to create new accounts easily
  • View QR codes to export existing accounts
  • Searchable, sortable listing of accounts
  • Manual entry account creation
  • Import/Export for backup and restore purposes
  • Relies upon AES-256 for on-device encryption
  • Supports Android 5.0 (and up)

OneTimePass is the reincarnation of the now-retired OneTimePad app. If you used OneTimePad, you should really migrate to this any other TOTP based application.
