How to Change Security Code in Whatsapp

If you’ve seen a message like “Your security code changed” in WhatsApp and wondered, “How do I change it?”—you’re not alone. The short version is this: WhatsApp usually doesn’t offer a manual “change security code” button. Those alerts are tied to security notification settings and to real changes such as new phones or reinstalling WhatsApp.

So let’s clear up two things people often mix together:

1) Security notifications (the alerts you see on your device)

2) Verification / password / two-step verification flow (how you prove it’s really your account)

Where WhatsApp security code change notifications are controlled

Those “security code changed” alerts are controlled by a setting called security notifications.

To find it on your phone, use this path:

1. Tap More Options (the three vertical dots)
2. Tap Settings
3. Tap Account
4. Tap Security notifications

From there, you can control whether WhatsApp shows those security alerts on your device.

Keep in mind: you’re not editing the code from this menu. You’re choosing whether WhatsApp displays notifications when the security setup changes.

How to turn on “Show security notifications on this device”

If you want WhatsApp to show these security-code change notifications on your current phone, turn the toggle on:

1. Go to More Options (three vertical dots) > Settings > Account > Security notifications
2. Turn on “Show security notifications on this device”

When this is enabled, WhatsApp will display the security notifications on that device, so you can see when something in the security setup has changed.

If you turned it off earlier, you may stop seeing those alerts even though changes can still happen.

Why WhatsApp says your security code changed with someone

Let’s break down the message you’re seeing.

A security code change on WhatsApp usually points to something like this:

• You changed phones (new device, or a different setup)
• Your contact changed phones
• Someone reinstalled WhatsApp
• Something was added or removed in the security setup

So if you see “Your security code is changed with someone,” it’s often WhatsApp’s way of saying: the security setup for that chat/account may now be using a different configuration.

Also, don’t assume the notification is happening because someone “blocked” you or anything like that. These alerts are about security changes and device/app changes, not a simple “good” or “bad” label about your specific contact.

Quick PAA answer: “How do I change my WhatsApp security code?”

In most cases, you can change the notification behavior (whether you see the alerts), not the code itself. Go to:

More Options (three vertical dots) > Settings > Account > Security notifications

then turn on “Show security notifications on this device.”

What to check if the message is unexpected (phone/app changes)

If you didn’t expect any security changes, start by looking at what changed on your side and your contact’s side.

Use this checklist:

• Did you switch to a new phone recently? Even if WhatsApp looks the same, the device change can trigger updates.
• Did you reinstall WhatsApp (or install it on a fresh setup)?
• Did your contact get a new phone or reinstall WhatsApp?
• Has anything been added or removed in WhatsApp on either end (for example, a fresh install counts as a major “reinstall” change)?

If you didn’t do any of those things, the change is more likely tied to the other person’s side (new phone, reinstall, or security setup changes).

WhatsApp question: “Why does WhatsApp say my security code changed with someone?”

Because the security setup for you or your contact likely changed. The usual causes are phone changes, reinstalling WhatsApp, or adding/removing something in the setup.

Where to change secret code in WhatsApp (what you can and can’t change)

Here’s where the wording gets confusing. “Secret code” sounds like something you should be able to edit manually.

But based on what you can control from the menu, the setting you’re really working with is:

More Options (three vertical dots) > Settings > Account > Security notifications

Then toggle “Show security notifications on this device.”

What you *can* do there

• Control whether you receive and see security-code change alerts on your current phone.

What you *can’t* usually do there

• Manually type in a new “security code.”
• Keep the same code after a major change like switching phones or reinstalling WhatsApp.

So if your goal is “stop getting these alerts,” start with the security notifications setting. If your goal is “make the code match again,” the real solution is usually making sure you both end up on the same expected setup (for example, after a new phone or reinstall, the alert may show up once because things changed).

I forgot my WhatsApp verification code. How can I reset it?

This part gets confusing because people see “security code changed” and then immediately assume it means the verification code.

They’re not the same thing.

• Security code change alerts relate to security notifications and changes to the security setup.
• Verification code (and the related password/two-step verification flow) is about proving your account so you can sign in.

Your information here doesn’t include a specific “reset verification code” button you can tap. What it does point to is using WhatsApp’s in-app account/verification/password flow, and following the prompts for verification and two-step verification settings.

If you’re stuck, the best next step is:

• Go back to WhatsApp account settings
• Use the prompts in the verification and two-step verification screens

If you tell me what screen you’re on (or share the exact error message), I can help you figure out whether you’re dealing with security notifications or verification/password.

Quick PAA answer: “I forgot my WhatsApp verification code. How can I reset it?”

Use WhatsApp’s in-app account/verification flow and any two-step verification prompts. The security-notification setting controls alerts, not the verification code reset process.

How to handle security notifications if you’re using a new device

If you’re on a new phone (or you recently reinstalled WhatsApp), security-code change alerts can be normal at first.

Here’s how to handle it without panicking:

1. Confirm you’re checking the right setting.

• More Options (three vertical dots) > Settings > Account > Security notifications

1. Decide whether WhatsApp should show alerts on this phone.

• Turn on “Show security notifications on this device” if you want them.

1. When you see alerts like “Your security code is changed with someone,” treat it as tied to one of these:

• phone change
• WhatsApp reinstall
• added/removed security setup changes

If you just moved devices and everything is working, these alerts may simply reflect WhatsApp adjusting to the new setup.

Quick checklist before you contact support

If you’re seeing repeated alerts, check this first:

• On your phone, go to More Options (three vertical dots) > Settings > Account > Security notifications
• Check whether “Show security notifications on this device” is turned on (or off, if you’re seeing fewer alerts than expected)
• Think back: did you or the other person recently:
• change phones
• reinstall WhatsApp
• add or remove something related to the security setup
• Make sure you’re not mixing up:
• security notifications (alerts about security code changes)
• verification code / password / two-step verification (account access and sign-in prompts)

If you’re seeing repeated WhatsApp security code change notifications, review your device/app changes and check your WhatsApp security notification settings. That usually explains what’s happening and helps you stop chasing the wrong setting.
