## Usage

A quick and simple usage of ``HOTP``:

```python
import otpauth

totp = otpauth.HOTP(b"user-secret")

# generate a code for now
code: int = totp.generate()

# you may want to convert it to string
str_code: str = totp.string_code(code)

# verify the code
totp.verify(code)  # => True
totp.verify(str_code)  # => True
```

## Install

Install with pip:

```shell
pip install otpauth
```
