QR codes not recognized by Google Authenticator

[Adriano Santoni]

Hi, any QR codes generated by calling GoogleAuthenticatorQRGenerator.getOtpAuthURL(...) are not detected by Google Authentication app. Here is an example:

https://api.qrserver.com/v1/create-qr-code/?data=URI+%5Bscheme%3Dotpauth%2C+userInfo%3Dnull%2C+host%3Dtotp%2C+port%3D-1%2C+path%3D%2Fissuer%3Auser%2C+queryParams%3D%5Bsecret%3D65DX5JBEFRXCLMS46FO57H67EWEMX3FA%2C+issuer%3Dissuer%2C+algorithm%3DSHA1%2C+digits%3D6%2C+period%3D30%5D%2C+fragment%3Dnull%5D&size=200x200&ecc=M&margin=0

Not even my Camera app can read the above QR code...

Other QR codes, e.g. those generated by Google, are instead recognized.

How comes that? Please advise...

this was never fixed?
i think this is because of 'margin=0'

if you change it to at least 'margin=1' it will work

hello,

your qr code is displaying a wrong otpauth URI.

When i scanned the QR with my cellphone camera this is the decoded text:

URI [scheme=otpauth, userInfo=null, host=totp, port=-1, path=/issuer:user, queryParams=[secret=65DX5JBEFRXCLMS46FO57H67EWEMX3FA, issuer=issuer, algorithm=SHA1, digits=6, period=30], fragment=null]
