I added the function getOTPUrl to get the otp:// url from the secret

since i don't want to send the screts to google, i created a function that outputs the otp: // url and then creates the barcode itself

The function works like the getQRCodeGoogleUrl function, but without the parameter $params.

Good thinking.

I would also update getQRCodeGoogleUrl() to call this new function, rather than duplicating the functionality.

I dont think so because the function is named getQRCodeGoogleUrl(). People who want a fast copy and paste solution are thinking that some data ist send to google.
