The short, direct answer is that, in most everyday situations, someone cannot see the specific websites you visit or the content you access when you use their hotspot. While a hotspot owner can see that you are connected and how much data you are using, standard encryption prevents them from seeing exactly what you are doing online, unless they have specialized monitoring tools.
What a hotspot owner can actually see
From a standard phone's hotspot settings, the realistic view is limited. On stock Android, you can see the number of connected users by navigating to Settings > Connections > Hotspot & Tethering > Mobile Hotspot, but there is no built-in method to view connected devices by name. On iOS and iPadOS, the Personal Hotspot feature uses WPA2/WPA3 Personal Security by default with a system-suggested, secure random password, and the host can see a list of connected devices. In both cases, the hotspot owner can monitor total data consumption and the number of devices connected, but not the specific activity on those devices. Some hotspots use a captive portal, which is a web page that prompts you to agree to terms and conditions before accessing the internet. The owner can customize this page and collect personal information provided by users, like email addresses or phone numbers. Hotspot owners may keep connection logs that show who has connected to their network, when they connected, and for how long.
The encryption that protects you
Two layers of encryption work together to keep your browsing private. First, most modern hotspots use WPA2 or WPA3 security, which encrypts all traffic between your device and the hotspot itself. This encrypts the data traveling between your device and the website's server. Because of this dual encryption, the hotspot owner sees only encrypted data packets, not the actual content of your browsing.
The VPN exception on iPhones
A critical detail for iPhone users: if you connect to an iPhone's Personal Hotspot, and the host has a VPN active on their device, that VPN does not cover your traffic. Apple's iOS platform is designed so that hotspot traffic does not go through a VPN enabled on the iOS host device itself. To protect your activity, you need a VPN active on your own connected device, not just on the host phone. This is a verified fact that contradicts some common assumptions about VPN protection on shared connections. Some hotspot owners can employ techniques to bypass VPN protection.
How to stay safe on someone else's hotspot
To protect your privacy when using another person's hotspot, follow these best practices:
- Always use a VPN on your own device. This creates an encrypted tunnel that even the hotspot owner cannot see into.
- Look for the HTTPS lock icon in your browser's address bar before entering any sensitive information. This ensures the connection to the website is encrypted.
- Avoid accessing sensitive accounts like banking or email when connected to an unfamiliar hotspot, as even encrypted connections can be vulnerable to advanced attacks.
- Keep your device updated with the latest security patches and software updates to minimize vulnerabilities.
- On Android, review your security and privacy settings by going to Settings > Security and Settings > Privacy (or a combined "Security & privacy" section) to check for potential risks and recommendations.
For those who own a hotspot and want to manage it securely, changing the Wi-Fi hotspot password will instantly stop all active connections. Apple devices also use randomized MAC addresses for Personal Hotspot in iOS and iPadOS, generating new random addresses whenever the network interface is started, which adds an extra layer of privacy for connected devices.

Frequently Asked Questions
Can hotspot users see my passwords and personal information?
If you are visiting websites that use HTTPS encryption, the hotspot owner cannot see your passwords directly. However, if you visit an unencrypted HTTP site or if the hotspot owner has sophisticated packet-sniffing tools, they could potentially intercept unencrypted data, including passwords.
Can the hotspot owner see my passwords?
Can someone track my online activities when connected to their hotspot?
Yes, a hotspot owner can see that you are connected and monitor the amount of data you use, but standard encryption prevents them from seeing the specific websites you visit or content you access. However, if they employ advanced monitoring tools or if you visit unencrypted sites, they could potentially track more of your online activities.
Is it illegal to use someone's hotspot without permission?
Yes, using someone's hotspot without their permission is generally considered unethical and could be illegal in some jurisdictions. It is always best to ask for permission before connecting to someone's personal hotspot.
Does a VPN on my own device protect me from the hotspot owner?
Yes, a VPN running on your own device encrypts all your traffic before it leaves your device, making it unreadable to the hotspot owner. This is the most effective way to protect your privacy on any shared network.
Can the hotspot owner see what apps I'm using?
With standard hotspot settings, the owner cannot see which specific apps you are using. They can only see the total amount of data being transferred. However, advanced monitoring tools could potentially identify app usage patterns based on data traffic characteristics.
How can I disconnect someone from my hotspot?
On both Android and iOS, the most effective way to instantly disconnect all users is to change your hotspot password. This will stop all active connections immediately. On Android, you can also see the number of connected users in Settings > Connections > Hotspot & Tethering > Mobile Hotspot.
