A time-based one-time password (TOTP) generator implementation in JavaScript.
This project is a modified version of russau's TOTP One-time password JSFiddle which fully works in the browser. It uses QRious for QR code encoding and jsSHA for SHA-1 generation (sha1.js v3.3.1).

You can also download the latest release and open index.html.
You can add query strings to automatically fill in the fields. They are based on the OTP Key URI format. The fields are:
| Query field | Description | Example value |
|---|---|---|
| label | String used to identify the account a key is associated with | GitHub: email@site.com |
| secret | Arbitrary key value encoded in Base32 | ABCDE |
| issuer | (Optional) The provider or service the key is associated with | GitHub |
It also accepts QRious options (except element and value) to customize the QR code:
| Query field | Description | Default value |
|---|---|---|
| background | Background color of the QR code | white |
| backgroundAlpha | Background alpha of the QR code | 1.0 |
| foreground | Foreground color of the QR code | black |
| foregroundAlpha | Foreground alpha of the QR code | 1.0 |
| level | Error correction level of the QR code (L, M, Q, H) | L |
| mime | MIME type used to render the image for the QR code | image/png |
| padding | Padding for the QR code (pixels) | None (auto) |
| size | Size of the QR code (pixels) | 200 |
