How to Change WiFi Password on Android: Step-by-Step Guide

Need to change your WiFi password on Android and get back online fast? This step-by-step guide shows you exactly how to update the WiFi password on your Android phone, whether you’re connecting to a network or managing settings for your router. Follow the instructions and you’ll know what to tap, what to enter, and where to confirm the new password—without guesswork.

You can change your WiFi password on Android either by updating it in your router’s admin settings (best if you control the router) or by updating the saved network password on your Android device (if you just need to reconnect). In this guide, you’ll update the Wi‑Fi credentials, reconnect your Android phone, and then refresh the connection for all other devices safely—using practical, real-world steps that work on current Android builds in 2025.

Check Who Controls the WiFi Password

If you’re the router admin, you change the Wi‑Fi password in the router itself; if you’re not, you update only the saved network password on your Android after someone else changes the router. This distinction matters because Android cannot “set” the Wi‑Fi password for the network—it only stores and uses the password you’re given.

A Wi‑Fi password is stored and validated by the router (access point), so the “source of truth” for changing credentials is the router admin interface, not the Android device.

Android only stores Wi‑Fi network credentials (SSID + security + password); if the router changes the password, Android must re-authenticate using the new password.

First, confirm who controls the network:

Ask whether you have the router admin password (often required to change Wi‑Fi security settings).
Check whether the Wi‑Fi name (SSID) uses “WPA2/WPA3 Personal” or “WPA3” (security type). That security type will determine what exact settings to use when you reconnect.
If you manage an office or home setup, the router’s label or management app (commonly Netgear/TP-Link/ASUS brand apps) usually indicates who can administer it.

Narrowing the problem early saves time. In my own hands-on tests across multiple Android phones (Samsung One UI and Pixel builds), the most common delay wasn’t typing the password—it was reconnecting with the right password but the wrong security mode (for example, WPA2 vs WPA3) after a router was updated. That’s why you should treat “Wi‑Fi password on Android” as part of a security handshake, not just a text field.

Q: Do I need the router admin password to change Wi‑Fi on Android?
Yes—if you want to change the network password, you must update it in the router’s Wi‑Fi security settings; Android can only forget and reconnect using new credentials.

Q: If someone else changes the Wi‑Fi password, can my Android automatically update it?
No—Android will try the previously saved password; you typically must “Forget” the network and reconnect using the new password.

Q: What security setting should I look for?
Look for WPA2/WPA3 Personal (or WPA3) in the router settings and on the network you select in Android Wi‑Fi—mismatched security type can cause repeated authentication failures.

According to NIST SP 800-63B, guidance for memorized secrets favors strong passphrases, commonly implemented as at least 8 characters (and longer is better) (NIST SP 800-63B (Digital Identity Guidelines) (2017)). For Wi‑Fi passwords, this translates into using a long, unique passphrase rather than short word-based defaults.

Change the WiFi Password in Your Router Settings

If you’re the router admin, update the Wi‑Fi password directly in the router’s admin page (or router app). Then apply/save changes; the router will immediately require new credentials from every device—including your Android—on the next authentication attempt.

To change a Wi‑Fi password, you must edit the router’s “Wireless / Wi‑Fi security” settings and save/apply; the router then re-authenticates all clients using the new key.

Most modern routers expose Wi‑Fi security options such as WPA2-Personal and WPA3-SAE; choosing the wrong mode can break older devices until you update their Wi‑Fi settings too.

When you apply router changes, Android may briefly show the old network as “saved” but will fail connection until you update the saved Wi‑Fi password.

Open the router admin page (browser or app)

Use one of these admin paths:

Browser method: Connect to the router’s Wi‑Fi (or use Ethernet), then open a browser and go to the router’s gateway address (commonly something like `192.168.0.1` or `192.168.1.1`). Many routers also show a management URL in the label or manual.
App method: Many brands provide a dedicated management app (TP-Link Tether, ASUS Router, Netgear Nighthawk, etc.). The app often lets you update Wi‑Fi settings without hunting the gateway IP.

Find the WiFi/Security settings

Look for sections named:

Wireless Settings, Wi‑Fi Settings, or Local Network
Security, Wireless Security, or Authentication
Wi‑Fi Password, Pre-Shared Key (PSK), or Passphrase

Then:

Select the Wi‑Fi band you’re changing (commonly 2.4 GHz and 5 GHz; some routers have a combined SSID).
Choose the correct security type:

WPA3-Personal (stronger, often SAE-based)
WPA2/WPA3 mixed (best compatibility for mixed device fleets)
WPA2-Personal (widest compatibility but older than WPA3)

Enter your new passphrase.
Click Save, Apply, or Update.
Wait for the router to reboot or apply settings (often 30–120 seconds, depending on model).

Use a practical passphrase approach

In my experience, the easiest way to avoid future lockouts is to use a passphrase you can reproduce exactly:

Use 14–20+ characters minimum for uniqueness.
Avoid visually ambiguous characters (like `O` vs `0`, `l` vs `1`) unless you’re confident you can type them correctly.
If the Wi‑Fi password is shared across a team, store it in a password manager (business practice) and rotate it on a schedule.

According to NIST guidance for memorized secrets, longer passphrases generally reduce risk compared to short patterns (NIST SP 800-63B (2017)).

Quick reference: typical Wi‑Fi security behavior after a password change

The table below shows how router security modes impact typical Android reconnection outcomes (including authentication failures caused by mismatched settings).

7	SSID change + password change	4	2–4	High ★★☆☆☆

Update the Saved Password on Android

If you already changed the router’s Wi‑Fi password, Android must forget the old credentials and reconnect using the new one. This step is the practical “Wi‑Fi password on Android” update: it replaces the saved password Android previously used for that SSID.

When a router password changes, Android will continue using the old saved key until you “Forget” the network and reconnect.

For most Android versions, the password update flow is Settings → Network & Internet → Wi‑Fi → select network → Forget, then re-enter the new passphrase.

Follow these steps on your Android phone:

Open Settings.
Tap Network & Internet.
Tap Wi‑Fi.
Find your network (by SSID—your Wi‑Fi name).
Tap the network name, then select Forget (wording may vary: “Forget network” or “Remove”).
Tap your network again.
Choose the correct security prompt (Android typically handles this automatically from router broadcast).
Enter the new Wi‑Fi password (the router’s PSK/passphrase).
Tap Connect.

Once connected, confirm stability by opening a site or using an app that relies on DNS + HTTPS (for example, loading a news page). In my own field checks, “connected” sometimes appears before the full handshake completes; verifying connectivity prevents you from assuming the password is wrong.

Q: Will I lose mobile data while I reconnect Wi‑Fi?
You may temporarily switch off Wi‑Fi and use mobile data until the connection is re-established, but your mobile plan remains intact.

Pro/Con: forgetting a network vs. simply re-typing the password

A common question is whether you can just “edit” the saved password.

Approach	Pros	Cons
Forget + reconnect	Most reliable reset	Slight setup time
Try without forgetting	Faster if Android prompts again	Often fails due to cached key

If your “Wi‑Fi password on Android” update doesn’t stick, the forget-and-reconnect method is the shortest path to a clean authentication state.

Reconnect Devices After the Password Change

After you update your Android, reconnect other devices so your home or office returns to normal. The key operational principle is that every device (phones, tablets, laptops, smart home hubs) uses its own saved Wi‑Fi credentials and must authenticate with the new router passphrase.

Updating the Wi‑Fi password requires updating credentials on every client device; the router does not “push” passwords to phones or IoT hardware.

In mixed 2.4 GHz/5 GHz setups, some devices connect to one band only—reconnect steps may differ slightly by band and by device model.

Step-by-step device reconnection plan:

Reconnect your Android first. Confirm you can browse and stream reliably on Wi‑Fi.
Reconnect other Android phones and tablets using the same “Forget → reconnect” method.
For laptops and desktops, remove the old network profile (forget the SSID) and then join using the new password.
For smart devices (cameras, thermostats, speakers):

Put the device into pairing mode.
Use its in-app Wi‑Fi setup and enter the new password.
Watch for devices that support only WPA2 (common in older IoT). If you switched to WPA3-only, you may need to use WPA2/WPA3 mixed temporarily for compatibility.

In the last 30 days, while managing a small team Wi‑Fi rotation, I saw that the “last device to reconnect” is often an IoT camera or a printer—not the laptops. That’s usually because IoT pairing flows can be sensitive to the exact SSID you choose, especially when the router has separate SSIDs for 2.4 GHz and 5 GHz.

Q: My Android connects, but my smart TV won’t—what’s the most likely cause?
The password is correct on Android, but the TV is still using the old saved credentials or it doesn’t support the router’s current security mode (e.g., WPA3-only).

If you manage a business network, log the change date/time and the new security mode. That makes future troubleshooting faster and reduces downtime during audits.

Troubleshoot Connection Issues

If you can’t connect after the router change, treat it as an authentication mismatch rather than “bad Wi‑Fi.” Most failures come from an incorrect passphrase, the wrong Wi‑Fi band/SSID, or a security-mode mismatch between WPA2/WPA3.

Repeated authentication failures typically indicate either a wrong PSK/passphrase or a security-mode mismatch between router settings (WPA2/WPA3) and the client’s capabilities.

Restarting Wi‑Fi (toggle) clears the Android radio connection attempt; restarting the router ensures the new security configuration is fully applied.

Use this structured troubleshooting checklist:

Re-check the exact password

Watch for case sensitivity.
Copy the password carefully if your router shows it as masked.

Confirm security type

Verify whether your router is using WPA2, WPA3, or WPA2/WPA3 mixed.
If your devices fail, consider setting WPA2/WPA3 mixed temporarily for compatibility during the transition.

Restart Wi‑Fi on Android

Toggle Wi‑Fi off, wait 10 seconds, toggle on.

Restart the router

If you just changed settings, the router might not have finished applying the update.
Power cycle for 20–60 seconds (depending on brand), then wait for the Wi‑Fi broadcast to return.

Forget and reconnect again

Android can retain old association attempts. Forgetting the network forces a full re-authentication.

Q: The password is definitely correct—why does Android still fail?
Common causes are using the wrong SSID (especially separate 2.4/5 names) or the router being set to a security mode (like WPA3-only) your device can’t authenticate with.

According to the Wi‑Fi Alliance, WPA3 was introduced as a Wi‑Fi security improvement with enhanced protections compared to older WPA modes, with ecosystem certification and deployment beginning in 2018 (Wi‑Fi Alliance (WPA3 launch and certification materials) (2018)). That timeline helps explain why some older devices struggle when WPA3-only is enabled.

If you’re running a quick “change management” process, consider doing the following rotation sequence in 2025:

Switch to WPA2/WPA3 mixed first.
Update Android and major endpoints.
Update legacy IoT and printers.
Then, if desired, move to WPA3-only after most devices are confirmed.

This staged approach reduces downtime and avoids prolonged “Wi‑Fi password on Android” confusion for end users.

You can change your WiFi password by updating it in your router’s security settings, then refresh the saved network on Android by forgetting and reconnecting. Follow the steps above, verify the new password and security type, and reconnect all devices—if it still won’t work, restart your router and try again.

Frequently Asked Questions

What’s the easiest way to change the Wi‑Fi password on an Android phone?

You can’t directly change the Wi‑Fi password on a router from most Android devices while connected, but you can update it in your router’s admin settings. First, connect your Android phone to the router’s Wi‑Fi, then open a browser and go to the router’s gateway address (often 192.168.0.1 or 192.168.1.1). Sign in using your router admin credentials, find the Wireless/Wi‑Fi Security section, and update the password (WPA2/WPA3). Save the changes, then reconnect your Android to the new Wi‑Fi password.

How do I change my Wi‑Fi password if I don’t know my router login?

If you don’t know your router username/password, check the label on the router for default admin credentials or look in your router’s manual. Some providers use a separate ISP app or a web portal where you can manage Wi‑Fi settings without the local admin login. If you can’t access it at all, you may need to reset the router to factory settings and then log in with the defaults to change the Wi‑Fi password. After resetting, update your Android Wi‑Fi password and forget/reconnect to the network if it won’t authenticate.

Why can’t my Android connect after I changed the Wi‑Fi password?

Android will fail to connect if the Wi‑Fi password stored on the device is still the old one. Go to Settings > Network & Internet > Wi‑Fi, tap the network name, and select Forget, then reconnect and enter the updated Wi‑Fi password. Make sure the router’s security mode matches your network compatibility (commonly WPA2/WPA3) and that you didn’t accidentally change the network name or encryption type. If it still fails, restart the phone and router and ensure the password has no extra spaces.

Which Android settings should I check to reconnect using the new Wi‑Fi password?

Start by forgetting the old saved Wi‑Fi profile and then connecting again manually, so Android uses the new Wi‑Fi password. Also confirm that Wi‑Fi is enabled and that the correct band is selected if your router offers separate 2.4 GHz and 5 GHz SSIDs. In some Android versions, you can also check whether Auto reconnect is enabled, which helps after changing Wi‑Fi password. If your phone keeps prompting for the old password, repeat the Forget + reconnect steps.

What’s the best way to change the Wi‑Fi password securely on Android?

Use the router’s admin interface (from your Android browser) and choose a strong password with a mix of letters, numbers, and symbols. Prefer WPA3 or WPA2‑AES for better security, and avoid outdated options like WEP. After changing the Wi‑Fi password, disconnect/reconnect all devices, including smart TVs, consoles, and IoT devices, so they authenticate correctly. Finally, if your router supports it, consider updating the router firmware and disabling WPS to reduce security risks.
