Problems and special cases
I have lost my phone, my PIN code or my QR code
Tell your employer straight away. They can deactivate the old code and give you a new one.
If you suspect that someone else is using your account, change your password from another device and report it to your employer immediately. If you have lost the device that generates your two-factor authentication codes, ask your employer to reset your two-factor authentication: they can do this from Cloketa.
