… but it gets complicated if you don’t know how to scan the code, first need to download a qr code reader app – since ios11 apple added the native function to scan qr code with camera app – some android device got a qr code reader pre-installed, other need to download it from app store

wifi qr code

enterprise facing other challenges to secure authenticate and trust devices

friends often request to join private wifi – tell the password ? no – enter your 12diget&complex$pezialC4ract3r password ? maybe not

create a qr code of your wifi incl. password, with services like qifi, your friends needs to “simply” scan the code

tested: for ios since ios11 it is working pretty easy, android devices with pre-installed qr code reader need to find the right app, but even my huawei ai powered camera is unable to recognize the qr code

update: since ios12 it is possible to add qr code scanner to control center to access from lockscreen and qr codes highlighted in camera while scanning

ios share wifi

even since ios11 apple added a feature to share wifi password between two ios devices, unless you have an ios device, the are some requirements to be meet

both ios devices need ios11 or newer installed
both ios devices need wifi and bluetooth enabled
your ios device must be actively connected to the wifi that the other device wants to join
both ios devices need physical proximity to each other
you must have each other in contacts list

be aware

that trusted devices are inside your network, may access your private services (sonos) or unsecured storages (nas) – better setup a separate guest wifi, with just access to the internet
shared passwords synced to google backup or icloud backup
