  A tiny package for generating 2FA QR codes and TOTP/HOTP codes in Nim





  nimble install twofa





  API reference


    



## 😍 Key Features

- 🔐 Generate TOTP and HOTP codes

- 📱 Create QR codes for easy setup with authenticator apps

> [!NOTE]

> This library is built on top of the [qr](https://github.com/ThomasTJdev/nim_qr) for QR code generation.

## Examples

Check out the [tests/*.nim](https://github.com/openpeeps/twofa/tree/main/tests) folder for examples of how to use the library.

### TODO

Currently you can use [otp](https://github.com/OpenSystemsLab/otp.nim) to verify TOTP and HOTP codes, but I plan to add that 

functionality directly into this library in the future.
