Modern smartphones have turned into universal tools that can replace many gadgets, including portable routers. The function mobile hotspot allows you to instantly distribute the Internet to a laptop, tablet or other phone when a landline network is unavailable. However, most users activate this feature without thinking about basic security measures, leaving their network open to outsiders.
An open hotspot is not just the risk of someone “hijacking your traffic.” Attackers can intercept transmitted data, inject malware into connected devices, or use your IP address for illegal activities. That is why setting up strong encryption is a critical step when organizing a wireless network via a smartphone.
In this article we will analyze in detail the process of setting and changing the password on different versions of the operating system Android. You will learn about the types of security protocols, network naming features and additional settings that will help make your access point as secure as possible from unauthorized access.
Principles of operation and types of Wi-Fi encryption on mobile devices
Before moving on to the settings, you need to understand what protection mechanisms a modern mobile operating system offers. By default, most smartphones use the WPA2-Personalprotocol, which is today the gold standard for home and mobile use. It provides reliable encryption of traffic between the access point and the client device.
Newer smartphone models equipped with modern radio modules can support the standard WPA3. This protocol eliminates some of the vulnerabilities of the previous version, especially in terms of protection against brute-force password guessing. However, it is worth considering that older devices may simply not see your network if you force only the third security standard.
When creating an access point, the system generates a unique network identifier, known as SSID. Initially, it often contains the name of the phone model, which is undesirable from a security point of view, since it provides information about potential vulnerabilities of a specific firmware. Changing this name to a neutral one is the first step towards anonymity.
⚠️ Attention: The WEP protocol has long been outdated and is considered hacked. If your device (usually very old models) has an option to select WEP, never use it. Choose only WPA2 or WPA3.
It is also important to distinguish between the concepts of a password for entering the phone settings menu and a password for the Wi-Fi network itself. Screen lock password protects your personal data in the device, while Access point password protects the Internet traffic transmission channel. Both of them must be complex and unique.
Use different passwords for the screen lock and for the access point. This will complicate the attacker's task, even if he somehow recognizes one of them.
Step-by-step guide for pure Android and Pixel
Owners of line smartphones Google Pixel and devices with a pure shell Android One have the most understandable and standardized settings interface. The path to the access point configuration here is logical and takes minimal time. First, you need to open the main settings menu of your device.
Go to the Network and Internetsection, and then select Access point and modem. Here you will see a switch to activate the feature and a settings menu. By clicking on Wi-Fi access point, you will be taken to the configuration screen where you can change all key network parameters.
In the window that opens, first of all, pay attention to the field "Network name". It is recommended to change it to something non-obvious that is not tied to your name or phone model. Next, find the field Password. The system may offer to generate a random set of characters, but it is better to set your own combination.
☑️ Checking the access point settings
When you enter a new password, the system will show it in clear text as long as you hold your finger on the "eye" icon. Make sure you remember the combination or write it down in a safe place. After entering, press the button Save. Now your network is protected, and connection is possible only after authentication.
It is worth noting that in some firmware versions the settings may be hidden in the quick menu. If you don’t find the item in the main settings, try holding down the Internet distribution icon in the notification shade - this often leads directly to the desired configuration menu.
Setting up Internet distribution on the Samsung One UI shell
The company's smartphones Samsung use a proprietary shell One UI, which has its own characteristics in the arrangement of controls. The logic of actions here is similar to pure Android, but the names of menu items may differ. To begin, open Settings and go to the section Connections.
In the list of options, find the item Mobile access point and modem. By clicking on it, you will see the current status of the function. To change security settings, you need to tap directly on the inscription Mobile access point, and not on the power switch.
In the configuration menu, you can change the network name and set a new password. The Samsung interface also allows you to adjust the frequency range: 2.4 GHz provides a greater range, and 5 GHz —a higher data transfer rate, but over a shorter distance. For maximum compatibility with older laptops, it is better to leave 2.4 GHz.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Band | 2.4 GHz | Best compatibility and range |
| Protocol | WPA2 Personal | Balance of security and speed |
| Timeout | 10 minutes | Battery saving |
| Max. devices | 3-5 | Connection stability |
One UI also offers the “Allowed Devices” feature. You can add MAC addresses of specific gadgets to the whitelist. In this case, even if someone knows the password, an outsider will not be able to connect to your network, since his physical address will not be authorized by the system.
What is MAC address filtering?
This is an access control method in which the access point checks the unique identifier of the network adapter of the connected device against a list of allowed addresses. This is a reliable method of protection, but it requires manual configuration of each new device.
After making all changes, do not forget to press the button Save at the top or bottom of the screen. The Samsung interface often requires explicit confirmation of changes, otherwise the settings may be reset when exiting the menu.
Setting features on Xiaomi and Redmi smartphones (MIUI/HyperOS)
Devices from Xiaomirunning on shell MIUI or new HyperOSoffer advanced access point management capabilities, but the interface may be less intuitive for beginners. Go to Settings and select section More or immediately Access point Wi-Fi in the main menu.
Click on item Setting up a Wi-Fi access point. Here you will see the usual fields for changing your name and password. A special feature of MIUI is the ability to configure the broadcast frequency and security standard in one window. Make sure that in the "Security" field the value is selected WPA2-Personal.
An interesting feature is the ability to set traffic limits. You can set a limit, upon reaching which the Internet distribution will automatically turn off. This is useful if you have a tariff with a limited gigabyte package, and you are afraid that the connected laptop will start downloading system updates.
⚠️ Attention: The MIUI interface often contains advertising recommendations and third-party services. Be careful when pressing buttons in the settings menu so as not to accidentally install an unnecessary application or click on an advertising link.
Also in the Xiaomi settings, the “Hide device” option is often found. If you activate it, your access point will not be visible in the list of available networks on other gadgets. You can only connect to it manually by entering the exact network name (SSID) and password. This increases the level of stealth, but complicates the connection for guests.
Do not forget that the path may differ on some firmware versions. If you do not find the settings through the main menu, use the settings search by entering the query “access point” or “hotspot”. System search will instantly redirect you to the desired section.
Requirements for the strength of the password and network name
Many users make the mistake of setting simple passwords like 12345678 or password. For modern hacking algorithms, such combinations are trivial and can be selected in a matter of seconds using specialized software. A strong password for an access point should contain at least 8 characters.
The ideal password creation formula includes a combination of upper and lowercase letters, numbers and special characters. For example, instead of the word internet it is better to use something like Int3rn3t#2026. At the same time, avoid using personal information: dates of birth, pet names or phone numbers, which can be easily found out from your social networks.
As for the network name (SSID), the opposite rule applies here. Don't make it too difficult to read if you plan to connect guest devices. However, avoid standard names like "AndroidAP" or "Samsung Galaxy S21". Such names tell the hacker your device model and potential firmware vulnerabilities.
It is best to use neutral names that do not attract attention. For example, "Office_Guest", "Home_Network_5" or even fictitious names that say nothing about the owner. This creates an additional level of security through non-obviousness.
A complex password protects against guessing, and a neutral network name hides information about your device from potential attackers.
Managing connected devices and blocking access
After setting a password, it is important to be able to control who exactly is connected to your network at the moment. In modern versions of Android, the access point menu usually displays a list of active clients. There you will see the name of the device, its MAC address and the amount of data transferred.
If you notice an unfamiliar device in the list, despite the password you have set, this may mean that the password has been compromised or shared with someone you know, who, in turn, shared it. In this case, you must immediately change the password in the access point settings.
When you change the password, all connected devices will be disconnected. You will have to re-enter the new combination on each gadget that you want to keep online. This is inconvenient, but is the only guarantee that an unauthorized user will lose access.
It is also recommended to limit the maximum number of connected devices. If you need to distribute the Internet to only one laptop, set the limit to 1 device. This will prevent a situation where neighboring gadgets connect to your network en masse, even if they somehow find out the password.
⚠️ Attention: The “Blacklist” function or blocking by MAC address is not available on all smartphones. If your model does not have this option, the only security measure is to regularly change the complex password.
Frequent problems and questions when setting up security
Users often encounter a situation where the device sees the network, enters the password, but the connection does not occur or is constantly reset. This may be due to incompatible encryption protocols. Try changing the security type from WPA3 to WPA2, since many older Wi-Fi adapters do not support the new standards.
Another common problem is the inability to find the network after changing the name to hidden. Remember that the hidden network does not broadcast its SSID. To connect, you need to select the “Add a network manually” option in the client’s Wi-Fi menu and enter the name and password exactly as they are set in the phone settings.
Sometimes after updating the system, the access point settings may be reset to factory settings. This is normal behavior with global firmware updates. Always check that the password is up to date after a major update to the operating system Android.
Is it possible to set a password only for certain devices?
No, the password is set the same for the entire network. However, you can use the "White List" (allowed devices) function, where only gadgets with specified MAC addresses are granted access, regardless of knowledge of the password.
Does a complex password affect Internet speed?
No, the length and complexity of the password do not affect the data transfer speed in any way. The speed depends on the level of the cellular signal, the load on the tower and the capabilities of the Wi-Fi module of your smartphone.
What should I do if I forgot the password for my access point?
You need to go to the settings of the access point on the phone itself that distributes the Internet. There the password is displayed in the "Password" field. If the field is hidden by dots, click on the "eye" icon to display it.
Is it safe to use a hotspot for online banking?
Yes, it is even safer than using open public Wi-Fi networks. Traffic in your personal access point is encrypted with the WPA2 protocol, which reliably protects banking application data from interception.
Why does the access point turn off after a while?
This is an energy saving function. In the access point settings, find the item “Timeout” or “Auto shutdown” and set the value to “Do not turn off” or increase the inactivity time if you need constant network operation.
