MinTOTP
=======

MinTOTP is a minimal TOTP generator written in Python.


Introduction
------------

TOTP stands for Time-Based One-Time Password. Many websites and services
require two-factor authentication (2FA) or multi-factor authentication
(MFA) where the user is required to present two or more pieces of
evidence:

  - Something only the user knows, e.g., password, passphrase, etc.
  - Something only the user has, e.g., hardware token, mobile phone, etc.
  - Something only the user is, e.g., biometrics.

A TOTP value serves as the second factor, i.e., it proves that the user
is in possession of a device (e.g., mobile phone) that contains a TOTP
secret key from which the TOTP value is generated. Usually the service
provider that provides a user's account also issues a secret key encoded
either as a Base32 string or as a QR code. This secret key is added to
an authenticator app (e.g., Google Authenticator) on a mobile device.
The app can then generate TOTP values based on the current time.
By default, it generates a new TOTP value every 30 seconds.

MinTOTP is a Python tool that can be used to generate TOTP values from a
secret key. Additionally, it exposes its functionality as module-level
functions for Python developers. It can be used on any system with
Python 3.4 or later installed on it.

What are file dependencies?

File dependency

Accesses the file system, and could potentially read sensitive data.

What is filesystem access?

Filesystem access

Package has a dependency with a floating version range. This can cause issues if the dependency publishes a new major version.

What are wildcard dependencies?

Wildcard dependency

Contains a dependency which resolves to a remote git URL. Dependencies fetched from git URLs are not immutable and can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are git dependencies?

Git dependency

Contains a dependency which resolves to a GitHub URL. Dependencies fetched from GitHub specifiers are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

What are GitHub dependencies?
