Sharing Internet from a phone Android A mobile hotspot is a convenient way to connect a laptop, tablet, or other gadget to the internet when a router is not available. However, an open hotspot without a password turns your smartphone into an easy target for hackers, ranging from traffic hoarding to personal data theft. According to research Kaspersky 2026, 38% of public Wi-Fi networks In Russia, these networks contain vulnerabilities exploited for phishing or MITM attacks. And your phone, when in tethering mode, is the same as a public network, unless it's protected.
In this article we will look at how to set a password for Wi-Fi distribution with Android on different firmware versions (from Android 10 to Android 14), what types of encryption to choose, and why standard WPA2-PSK It still remains the gold standard for security. And what to do if your phone won't let you change your password or your hotspot suddenly disconnects. Spoiler: on some models Xiaomi And Samsung You must first reset your mobile network settings to unlock hotspot settings editing.
Why is it important to set a password when sharing Wi-Fi from your phone?
An open access point is like an unlocked door to your digital life. Here are three real threats you'll face without a password:
- 🔍 Traffic interception: Attackers can see what websites you visit (even in
HTTPS, if they use vulnerabilities like KRACK). Particularly dangerous for online banking and instant messaging. - 📱 Traffic consumption: Connected devices will eat up your mobile data. For example, an update Windows 11 through your hotspot can spend up to 3 GB at a time.
- 🚨 Legal risksIf someone downloads pirated content or distributes malware through your network, you, as the owner of the IP address, may be held accountable.
But also a weak password (for example, 12345678 or qwerty) won't save you: modern brute-force programs crack such combinations for less than 10 minutesTherefore, it is important not only to install protection, but also to configure it correctly.
⚠️ Attention: On some mobile operator tariffs (for example, Tele2 or Yota) Internet sharing via hotspots is blocked or charged separately. Check the terms in your personal account to avoid unexpected charges.
What types of encryption does Android support for hotspots?
When setting up a password for distributing Wi-Fi with Android You'll be asked to select a security type. Here's what these abbreviations mean and which option is best:
| Encryption type | Security level | Compatibility | Notes |
|---|---|---|---|
WPA3-Personal |
⭐⭐⭐⭐⭐ | Devices with Android 10+ And iOS 13+ | The most reliable, but may not be supported by older gadgets. |
WPA2-PSK (AES) |
⭐⭐⭐⭐ | All devices | Gold standard. Use if WPA3 unavailable. |
WPA-PSK (TKIP) |
⭐⭐ | Obsolete devices | Vulnerable to attacks KRACK. Not recommended. |
Open network |
❌ | All devices | No protection. Use for testing purposes only. |
If your phone only offers WPA2-PSK, that's normal - this protocol is still considered secure with the correct password. But WPA-PSK (or simply WPA) It's better not to choose: hacking it takes only a few hours on a regular laptop.
Step-by-step instructions: how to set a password for Wi-Fi sharing on Android
The algorithm of actions differs slightly depending on the version Android and the manufacturer's shells (MIUI, One UI, ColorOS etc.). Below is a universal instruction that is suitable for 90% of devices (from Samsung Galaxy S21 to Redmi Note 12).
Turn on mobile Internet (3G/4G/5G)

Disable your VPN (it may block distribution)
Remember your current password (if you had one)-->
Step 1: Open the hotspot settings
Go to the menu:
Settings → Connections → Hotspot & Tethering → Mobile Hotspot
On some phones (eg. Xiaomi or Realme) the path may look like this:
Settings → SIM cards and mobile networks → Portable hotspot
Step 2: Set up your network name (SSID) and password
In the access point menu, find the fields:
- 📛 Network name (SSID): Come up with a unique name (don't use personal information!). Example:
HomeHotspot_5Ginstead ofIvanov_iPhone. - 🔐 Password: Minimum length - 8 characters. Optimal: 12+ characters with numbers, capital letters and special characters (for example,
7K#pL9!mQ2$v). - 🔒 Security type: Select
WPA2-PSKorWPA3-Personal(if available).
On Samsung Galaxy With One UI 5.0+ You may need to click Customize or Advanced first to see the editing fields.
Step 3: Save the settings and enable the hotspot
After entering the data:
- Click Save or Done.
- Turn on the Mobile Hotspot switch.
- Connect your device to the new network using the password you set.
Customization features for popular brands
Manufacturers often modify the standard Android, adding their own features (or limitations). Let's look at the nuances for top brands.
Samsung (One UI)
On phones Samsung Galaxy (For example, S23 Ultra or A54):
- 🔄 To change your password, first turn it off access point, then tap Configure.
- 📡 You can enable it in the "Additional" menu
5 GHzfor more stable distribution (if supported). - ⚠️ On some firmware versions One UI 4.1 The password is reset after the update - check it after updates.
Xiaomi (MIUI)
On Redmi, Poco or Xiaomi 13T:
- 🔒 By default, the password is a combination of
8 digits. Be sure to change it. to a more complex one! - 📵 If the password field is locked, go to
Settings → Storage → Clear datafor the "Access Point" application. - 🔄 In MIUI 14 Added the "Auto-disable" option - disable it if you want constant distribution.
Google Pixel (Stock Android)
On the "clean" Android (For example, Pixel 7 Pro):
- 🔐 Default is
WPA3-Personal- don't change it toWPA2without reason. - 📶 In the settings, you can limit the number of connected devices (maximum - 10).
- 🔄 The password can be changed directly in the hotspot menu without additional confirmation.
⚠️ Attention: On phones Huawei With EMUI 12+ Wi-Fi distribution may be blocked when active Huawei Mobile ServicesDisable it in your account settings if the hotspot doesn't turn on.
What to do if you can't set a password
Sometimes the system won't let you change your password or won't save your settings at all. Here are typical causes and solutions:
| Problem | Possible cause | Solution |
|---|---|---|
| Password field is inactive | Operator or firmware limitation | Reset network settings in Settings → System → Reset |
| The password is reset after reboot. | Firmware bug (often on MIUI) | Update the firmware or set a password via ADB |
Cannot select WPA3 |
Outdated hardware or firmware | Use WPA2-PSK (AES) |
| The access point turns off after 5-10 minutes | Energy saving | Add "Access Point" to battery optimization exceptions |
If nothing helps, try resetting your network settings to factory defaults:
Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings
After this, the hotspot settings will become available for editing.
How to set a password via ADB (for advanced users)
If the phone interface does not allow you to change the password, you can do it through ADBConnect your phone to your PC, enable USB debugging, and run the following command:
adb shell settings put global tether_dun_required 0
adb shell am broadcast -a android.intent.action.TETHER_STATE_CHANGED
After this, restart your phone and try setting up the hotspot again.
How to create a secure hotspot password
A weak password negates all security efforts. Here are the rules for creating a strong password:
- 🔢 Length: Minimum 12 characters (optimally 16+).
- 🔤 Complexity: A combination of uppercase and lowercase letters, numbers and special characters (
!@#$%). - 🚫 What to avoid:
- Dates of birth, names, nicknames of pets.
- Popular sequences:
qwerty,12345678,password. - Repeating characters:
aaaa1111.
Examples of strong passwords:
C0ff33$tr0ng!(coffee + numbers + special characters)V3ry_L0ng_P@ssw0rd(phrase with letters replaced by numbers)9T#kL2mPq7$v(random combination)
To avoid forgetting your password, save it in a password manager (for example, Bitwarden or Google Password Manager) or write it down on paper (but don’t keep it near your phone!).
Additional security measures when distributing Wi-Fi
A password is just the first step. To maximize your network security, take a few more steps:
- 🔄 Change your password regularly: Once every 1-2 months (or after connecting unknown devices).
- 📵 Turn off the hotspotwhen it's not needed. A constantly active access point drains battery power and increases security risks.
- 👥 Limit the number of devices: In the hotspot settings, set the limit (for example, 3 devices).
- 🛡️ Use VPN on connected devices: This encrypts traffic even on a secure network. Recommended ProtonVPN or Windscribe.
If you are distributing the Internet in a public place (for example, in a cafe or coworking space), turn on hiding SSID (The "Hidden Network" option in the hotspot settings.) This won't make the network completely invisible to experienced users, but it will reduce the number of accidental connections.
⚠️ Attention: On Android 12+ some operators (for example, MTS or Beeline) block Wi-Fi hotspot access on unlimited internet plans. If the hotspot doesn't activate, check your plan's terms or call support.
FAQ: Frequently asked questions about passwords for Wi-Fi hotspots on Android
Is it possible to set a password on an already working hotspot without disabling it?
No. To change your password, you first need to turn off access point, make changes, and then re-enable it. All connected devices will be disconnected and will need to reconnect with the new password.
Why won't my phone let me select WPA3?
It depends on two factors:
- Hardware support: Old chipsets (eg. Qualcomm Snapdragon 6xx until 2019) may not support
WPA3. - Firmware: The manufacturer may have disabled this option in the settings (often found on budget phones) Nokia or Tecno).
In this case, use WPA2-PSK (AES) - This is a safe alternative.
How do I find out who is connected to my hotspot?
Standard means Android They don't show a list of connected devices. But there are workarounds:
- Use apps like Fing or NetScan (scan the network and show MAC addresses).
- On some phones Samsung In the hotspot menu there is a section called “Connected devices”.
- Check your traffic: if your internet speed has dropped sharply, it's possible that someone else has connected to the network.
What should I do if I forgot my hotspot password?
There are two ways to restore access:
- View in settings: Go to the hotspot menu - the current password is displayed there (it may be hidden under "show").
- Reset settings: If the password is not displayed, reset the network settings (see instructions above).
On Xiaomi The default password often matches the last 8 digits of the phone's IMEI (find out the IMEI: *#06#).
Is it possible to share Wi-Fi without a password, but with restrictions?
Technically yes, but that's unsafeAlternative options:
- Guest network: Some phones (eg. Google Pixel) allow you to create a separate guest hotspot with limited access.
- MAC filtering: In manual mode, you can allow connections only to certain devices (but this does not protect against MAC spoofing).
- Time limit: Set the hotspot to turn off automatically after 30-60 minutes.
However, even these measures will not replace a full password.
