Remove Stored Wi-Fi Networks (Apple)
The networks your iPhone remembers are a travel history: hotels, offices, airports, a friend's flat. Clearing the list is less alarming than the menu makes it look.
Your phone keeps a list of every Wi-Fi network it has joined, and it uses that list to reconnect automatically. That list is a travel history: hotels, offices, airports, a friend's flat, the clinic you visited once. Anyone who can read the names your device has stored, or observe it looking for them, learns where you have been.
Network names are also mappable. Public wardriving databases such as Wigle.net hold the physical coordinates of millions of access points, so a stored network name is frequently a street address.
iPhone and iPad
Settings → Wi-Fi → tap Edit in the corner of the screen. This is the step most people miss: the main Wi-Fi screen shows only what is in range, and Edit reveals the full list of networks known to the device.
Tap the More Info button next to a network, then Forget This Network, then Forget to confirm. Repeat for anything you do not need stored.
Mac
Apple menu → System Settings → Wi-Fi in the sidebar → scroll down and click Advanced to see the networks known to your Mac. Click the More Options button next to a network, choose Remove From List, then Forget to confirm.
If you want to clear everything at once
Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. The warning looks severe and the phone restarts, but it only clears network configuration: saved Wi-Fi networks and passwords, cellular settings and VPN configurations. Your photos, messages and apps are untouched.
Use this when the stored list is long enough that pruning it by hand is not realistic. You will need to re-enter passwords for the networks you actually use.
Keeping the list short
The list grows back. Two habits keep it manageable: turn off Auto-Join for networks you use once rather than forgetting them later, and get in the habit of forgetting a guest or hotel network as you check out rather than months afterwards.
