 AutoName: FreeOTP Plus
-Description: |-
-    FreeOTP Plus is a fork of FreeOTP provided by Red Hat with the following
-    enhancements:
-
-    * Export settings to Google Drive or other document providers
-    * Import settings from Google Drive or other document providers
-    * Supports Android 6.0 permissions
-    * Enhanced UI with material design
-
-    FreeOTP is a two-factor authentication (2FA) application for systems utilizing
-    one-time password protocols (OTP). Tokens can be added easily by scanning a
-    QR-code or by manually entering in the token configuration.
-
-    FreeOTP implements open standards. This means that no proprietary server-side
-    component is necessary: use any server-side component that implements these
-    standards — for example <a href="http://www.freeipa.org">FreeIPA</a>, which uses TOTP. Any
-    standards-compliant implementation will work. Currently, FreeOTP provides
-    implementations of HOTP (RFC 4226) and TOTP (RFC 6238).
