What behaviour is observed?

the QR code can not be scanned, unless the image background is somehow changed to white.

Expected behaviour

the QR code is susessfullty scanned

To Reproduce

1. enable 2fa
2. click on link
3. link will open in browser to show a qr code with no margin/border and a black background
4. the qr code can not be scanned

alternatively:

• change the page background color, using dev tools, to white, then the code can be scanned.
• or in the url change 'margin=0' to 'margin=10', and the code can now be scanned.

Configuration

i believe the error lies in one of these:

import com.warrenstrange.googleauth.GoogleAuthenticator;
import com.warrenstrange.googleauth.GoogleAuthenticatorKey;
import com.warrenstrange.googleauth.GoogleAuthenticatorQRGenerator;
import com.warrenstrange.googleauth.IGoogleAuthenticator;

specifically this:
GoogleAuthenticatorQRGenerator.getOtpAuthURL

the margin is hardcoded:
private static final String TOTP_URI_FORMAT =
"https://api.qrserver.com/v1/create-qr-code/?data=%s&size=200x200&ecc=M&margin=0";

in the following file:
https://github.com/wstrange/GoogleAuth/blob/master/src/main/java/com/warrenstrange/googleauth/GoogleAuthenticatorQRGenerator.java

suggestion: if that repo (https://github.com/wstrange/GoogleAuth) is no longer maintained,
you could fork it and update the margin to 'margin=10' (easy)
or add a parameter to require a margin value when using the function, just like the server name.

or you could add this repo that i forked just now and added the small change to, (margin=0 => margin=10)
