## What it is
MinTOTP is a minimal TOTP (time-based one-time password) generator written in about 20 lines of Python, usable as a CLI tool or as importable module functions. It generates 2FA codes from Base32 secret keys on any system with Python 3.4+.

## Use cases
- generate TOTP 2FA codes from the command line
- generate one-time passwords from a Base32 secret key
- replace a mobile authenticator app with a Python script
- generate TOTP values programmatically in Python
- decrypt a GPG-encrypted 2FA secret and generate codes
- learn how the TOTP/HOTP algorithm works from minimal source code

## When to choose
- you want a tiny, auditable TOTP generator with minimal dependencies
- you need to generate 2FA codes on a headless server or any machine with Python 3.4+
- you want to embed TOTP generation in Python code via module-level functions

## When to avoid
- you need a full-featured authenticator app with QR scanning, multi-account UI, or encrypted storage
- you need HOTP counter-based workflows or advanced OTP features beyond basic TOTP generation
