I know that it is not possible to obtain the device name (e.g. PC-Francesco) but I was wondering what an alternative solution could be to obtain a unique string for the device. I need it to then make a comparison during login and check if the device is set in the db as blocked. I was thinking of merging the provider name + operating system + device type. Do you have any other better solution? Type is it possible to get the serial number or the model number of the device? thanks i hope you can help me

  • There's no way to get a truly unique string from a device. There can always be collisions. That's a good thing when it comes to privacy though. To try and get it as unique as possible, you can just grab as much info client info as possible from the `$_SERVER`-variable and hash it. – M. Eriksson Jun 29 '20 at 09:33
