freeotp is a twofactor authentication application for systems utilizing onetime password protocols with support for ?android (3.0 or later) and ?ios (7 or later). tokens can be added easily by scanning a qrcode or by manually entering in the token configuration.

freeotp implements open standards. this means that no proprietary serverside component is necessary: use any serverside component that implements these standards. we personally recommend ?freeipa, which uses totp. however, any standardscompliant implementation will work. currently, freeotp provides implementations of ?hotp and ?totp.
