On android when you go to the wifi settings you're currently connected to there should be a setting for randomizing mac address per connection or per network. If you change it to per connection, once you disconnect and reconnect your mac address should change. On per network, it will randomly generate the mac address for the first connection and keep that address for that wifi forever.
Excellent explanation, thank you. Never knew what that difference was.
Yeah, recently I was on school wifi and it kept bothering me to log in and figured I needed to switch to per network or it would bother me everytime to sign into the captive portal.
Thanks for asking the question! I've never needed to know it, and I've done enough android tinkering that I'm fairly sure I could find it quite easily if needed, but I enjoy my social media being peppered with bits of learning wherever possible. I'm a big fan of ambient curiosity
Same here. Thanks :)
I think per connection is a GrapheneOS thing unless I'm wrong
Graphene just changed it to be enabled by default
But maybe they hat this feature earlier than AOSP
Yeah, on Android 12 I can only choose between "randomized MAC" and "phone MAC". Doesn't specify if it's randomized per network or connection, but I'd guess it's per network.
On stock (Pixel) Android, if you enable Developer Options, there is a setting under Networking called "Wi-Fi non-persistent MAC randomization" that randomizes the MAC per connection for networks that have randomization enabled.
Samsung's OneUI does this by default for all connections .
