## Usage
```typescript
import { decodeMigrationUri } from "gauth-decode";

void decodeMigrationUri("otpauth-migration://offline?data=Ch8KBdFBKZJTEgpUZXN0IFRva2VuGgQyRkFTIAEoATACEAEYASAAKIji6ej7%2F%2F%2F%2F%2FwE%3D").then(result = console.log(result));
```
output:

```javascript
[
    {
        algorithm: "ALGO_SHA1",
        digits: 1,
        issuer: "2FAS",
        name: "Test Token",
        secret: "0UEpklM=",
        secretBase32: "2FASTEST",
        type: "OTP_TOTP"
    }
]
```

## Sample data
A sample [TOTP](https://en.wikipedia.org/wiki/Time-based_one-time_password) QR code from [2FAS](https://2fas.com/check-token/):

Contained URI data: `otpauth://totp/Test%20Token?secret=2FASTEST&issuer=2FAS`

The same sample data exported from Google authenticator:
