pyotp is a Python library for generating and verifying one-time
passwords. It can be used to implement two-factor or multi-factor
authentication methods in web applications and in other systems
that require users to log in.

A script /usr/doc/pyotp-$VERSION/gen_totp.py is provided to generate
TOTP codes.  Suggested usage is to copy to ~/.local/bin/ and edit the
file to define your TOTP secrets.  See the comments in gen_totp.py for
more details.
