The iPhone hotspot security type is WPA2/WPA3 Personal by default, using a system-suggested random password to protect your connection. This means your iPhone Personal Hotspot provides strong encryption and automatic password generation, making it safe for connecting your other devices.
What iPhone hotspot security type does Apple use?
Apple documents that Personal Hotspot on iOS and iPadOS uses WPA2/WPA3 Personal Security by default. The system also provides a default secure and random password for the access point, which is generated automatically when you turn on the hotspot. This combination ensures that your cellular data connection is shared with strong encryption and that unauthorized devices cannot guess the password.
How Maximize Compatibility changes the security
If you turn on Maximize Compatibility on an iPhone 12 or later, the hotspot switches to WPA2 Personal and uses only the 2.4 GHz band. This setting is useful when older devices cannot connect to WPA3 or the 5 GHz band, but it reduces the security level from WPA3 to WPA2. You should only enable this option if a device fails to connect with the default settings.
How to turn on your iPhone Personal Hotspot
- Open Settings and tap Personal Hotspot.
- Alternatively, go to Settings, tap Cellular, then tap Personal Hotspot.
- On some iPhones, you may need to tap Cellular, then Set Up Personal Hotspot, and follow the onscreen instructions.
- Tap Allow Others to Join.
You need an iPhone or iPad (Wi‑Fi + Cellular) with an activated network provider plan that includes Personal Hotspot service to provide the hotspot. Once enabled, other devices can see your hotspot in their Wi-Fi settings and connect using the password shown on your iPhone’s screen.
How other devices connect and stay protected
Other devices can connect to your Personal Hotspot using Wi-Fi settings, Bluetooth, or a USB cable. For Instant Hotspot, iPhone and iPad devices that support this feature use Bluetooth Low Energy (BLE) to discover and communicate with devices signed in to the same Apple Account or Family Sharing group. Apple says Instant Hotspot makes the hotspot discoverable from Control Center on the iPhone. The BLE requests are encrypted, and Family Sharing hotspot information is shared using ECDH (Curve25519) authenticated with device-specific Ed25519 public keys. This means that even the discovery process is protected against eavesdropping. Apple documents no Android menu path, Android setting name, or Android version requirement for connecting to an iPhone hotspot.
What the hotspot cannot do
Your iPhone Personal Hotspot can only share the cellular internet connection on your iPhone. You cannot connect your iPhone to a Wi-Fi network and then share that network with another device.
Simple steps to keep your hotspot secure
- Use the system-suggested random password or set a strong custom password that includes a mix of letters, numbers, and symbols.
- Keep your iPhone updated to the latest iOS version, as security updates often include improvements to hotspot and Wi-Fi protections.
- Disable auto-join for unknown networks on your other devices so they do not accidentally connect to an unsecured hotspot.
- If you need help with hotspot basics and troubleshooting, refer to Apple’s support documentation for Mobile Hotspot Basics and Troubleshooting.
Frequently Asked Questions
Does the iPhone hotspot use WPA3 on all iPhone models?
No. The default is WPA2/WPA3 Personal, but older iPhone models may only support WPA2. The actual security level depends on the device connecting to the hotspot and whether Maximize Compatibility is enabled.
Can I see which devices are connected to my hotspot?
Yes. On your iPhone, the Personal Hotspot screen shows the number of connected devices. You can also tap the status bar to see the device name and connection type for each connected device.
Does using a hotspot drain the iPhone battery faster?
Yes. Sharing your cellular connection uses additional power. To extend battery life, consider using a USB cable to connect devices instead of Wi-Fi, as the wired connection is more power-efficient.
Is the hotspot password the same as my iPhone passcode?
No. The hotspot password is separate from your iPhone passcode. You set it when you turn on Personal Hotspot, and it is used only for devices connecting to the hotspot network.
Can I use my iPhone hotspot while on a call?
Yes, on most carrier networks. Your iPhone can maintain a cellular call and share data through the hotspot at the same time, though data speeds may be slower during the call.
