If your iPhone keeps reconnecting to a public hotspot you no longer trust, forgetting that network is the fastest way to stop it.
This guide explains how to forget public WiFi network on iPhone, when it helps, and what to do if the option seems missing.
Why forgetting a public WiFi network matters
Public WiFi networks in coffee shops, airports, hotels, libraries, and transit hubs are convenient, but they can also be inconsistent and less secure than private home networks. iPhone stores network details so it can reconnect automatically, which is useful until a hotspot becomes slow, captive, or untrusted.
Forgetting a network removes the saved connection profile from your device.
That means your iPhone will stop auto-joining it and will no longer use the stored password or connection preferences for that network.
- Stops automatic reconnection to a public hotspot
- Removes saved password and network preferences
- Helps reduce accidental use of unstable or risky WiFi
- Can fix repeated login prompts or connection glitches
How to forget public WiFi network on iPhone
The process is simple and works on modern versions of iOS.
If the network is currently nearby, you can forget it directly from the Wi-Fi settings.
- Open Settings on your iPhone.
- Tap Wi-Fi.
- Find the public network under My Networks or the list of available networks.
- Tap the info icon, shown as a blue i in a circle.
- Tap Forget This Network.
- Confirm by tapping Forget.
After that, the iPhone will treat the network like a new one the next time it appears.
You will need to select it manually and enter any required login details again.
What happens after you forget a WiFi network?
Forgetting a network does more than remove it from your list.
It clears the saved credentials and prevents automatic reconnection unless you join again.
- Your iPhone will no longer auto-connect to that network.
- Any password or captive portal data saved for that network is removed.
- The network may still appear in the list of available WiFi hotspots if it is in range.
- Your iPhone can still connect to other known networks, including home, work, or personal hotspot connections.
If the network uses a sign-in page, forgetting it can also help if the portal is stuck, expired, or loading incorrectly.
How to make sure your iPhone does not reconnect automatically?
Sometimes you do not want to forget a network completely, especially if you may need it again later.
In that case, you can reduce the chance of auto-joining without removing the profile immediately.
Turn off Auto-Join
In the Wi-Fi details screen, look for Auto-Join and switch it off.
This keeps the network saved but stops the iPhone from joining it on its own.
Use Low Data Mode with caution
Low Data Mode can reduce background network activity on supported connections, but it does not replace forgetting a network.
It is a data-saving tool, not a privacy tool.
Disable Ask to Join Networks if needed
Under Settings > Wi-Fi, iPhone can prompt you about nearby networks.
Adjusting this setting may reduce unwanted prompts, though it will not erase previously saved networks.
How to remove a public network that no longer appears?
Sometimes a network is saved on your iPhone even when it is not currently in range.
In that case, you may not see the familiar info button unless the hotspot is available.
There are a few ways to handle this.
- Wait until the network is in range again, then forget it from Wi-Fi settings.
- Reset network settings if you want to remove multiple saved networks at once.
- Check whether the device is managed by your employer or school, which may restrict changes.
If you choose Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings, your iPhone will erase saved Wi-Fi networks, passwords, and related network settings.
This is broader than forgetting one public WiFi network and should be used only when necessary.
When forgetting the network may not be enough
Removing a network from your iPhone does not erase data that may already have been transmitted while you were connected.
If you signed in on an untrusted hotspot, consider additional safety steps.
- Change passwords for accounts accessed on the network if you suspect exposure.
- Enable two-factor authentication on sensitive accounts such as email, banking, and Apple ID.
- Use HTTPS websites and apps that encrypt traffic end to end whenever possible.
- Turn off Wi-Fi when you do not need it in dense public areas.
Apple’s built-in privacy features and modern encryption help, but public WiFi should still be treated with caution, especially on open networks without strong authentication.
Can a public WiFi network reappear after forgetting it?
Yes.
If you revisit the same location, the network name may show up again because it is being broadcast by the hotspot, not because it is still saved on your phone.
The important difference is that your iPhone will not automatically join it unless you tap it and reconnect.
If your device appears to reconnect anyway, check for other saved networks with similar names, look for configuration profiles, or review whether Wi-Fi Assist and known-network settings are affecting your connection behavior.
Tips for managing public WiFi on iPhone
Good Wi-Fi hygiene on iPhone is mostly about controlling which networks are saved and reducing unnecessary exposure.
A few practical habits make a noticeable difference.
- Forget public hotspots after short-term use.
- Keep Auto-Join disabled for networks you only use occasionally.
- Review saved networks periodically in Wi-Fi settings.
- Prefer personal hotspots or trusted private networks for sensitive activity.
- Use a VPN on public WiFi when appropriate for an added layer of encryption.
These steps are especially useful for frequent travelers, remote workers, and anyone who moves between airports, hotels, and shared workspaces.
When to use Reset Network Settings instead of forgetting one network
Forgetting one public network is best when you only need to remove a specific hotspot.
Reset Network Settings is better when Wi-Fi behavior is broadly broken, connection attempts keep failing, or you want a clean slate across all saved networks.
- Use Forget This Network for one unwanted public hotspot.
- Use Reset Network Settings for repeated system-wide connection problems.
- Use Auto-Join controls when you want a network saved but not automatic.
Understanding the difference saves time and prevents unnecessary loss of trusted Wi-Fi passwords.
