WhatsApp now lets you add a PIN to your username, ensuring that only people who know the code can send you a message. This feature is part of WhatsApp's new username system, which allows you to be contacted without sharing your phone number. But if your username becomes widely known, you might start receiving messages from strangers. That's where PIN protection comes in.
By setting a PIN, you add an extra layer of security: even if someone knows your username, they'll need the PIN to initiate a chat with you. This is perfect for when your username gets shared more than you intended and you want to control who can reach you.

What Is a WhatsApp Username and Why Protect It?
Your WhatsApp username is a unique handle that others can use to contact you without needing your phone number. It's similar to usernames on other messaging platforms. When you reserve a username, you can choose to let people contact you by that name.
However, usernames can easily spread—through social media, forums, or direct sharing. Once it's out there, anyone can message you. Adding a PIN ensures that only those you trust (or those you give the PIN to) can start a conversation.
How to Set Up a PIN for Your Username
Setting up a PIN is straightforward. First, ensure you've already reserved a username. If you haven't, you'll be prompted to create one. Once you have a username, follow these steps:
- Open WhatsApp and go to Settings.
- Tap on Account (the section with the key icon).
- Select Username under "Your account".
- On the username screen, tap Contact me by username.
- Here, you can define who can contact you and enable PIN protection.
You'll be able to set a PIN that others must enter before sending you a message. This PIN is required only for the first message—once someone enters it correctly, they can chat with you normally.
Who Needs the PIN and When
The PIN is required only when someone tries to message you for the first time using your username. If you've already chatted with someone, they won't need the PIN again. This means you can share your username publicly but still control who can initiate contact. The longer history behind the story is traced in WhatsApp Usernames: What They Are and How to Reserve Yours. More on the surrounding debate is collected in How to PIN Protect Your WhatsApp Username for Secure Messaging.
You can share the PIN with friends, family, or colleagues so they can reach you. For everyone else, your username alone won't be enough to send a message. The background to this story is set out in WhatsApp Blue Ticks: Reclaim Your Peace and Privacy Now. A related thread runs through WhatsApp Usernames: The Real Reason Behind the Feature. Earlier coverage in 8 ways to ensure your business is secure in 2026 People Get Wrong shows how the argument developed.
Benefits of PIN Protection

- Spam reduction: Prevent unsolicited messages from strangers who find your username.
- Security: Adds a barrier against harassment or unwanted contact.
- Flexibility: You can still use your username publicly without exposing your phone number.
- Easy setup: The process is quick and integrated into WhatsApp settings.

What to Watch For
Remember that the PIN is required only for the first message. If you share the PIN with someone, they can message you anytime. Also, if you forget your PIN, you may need to reset it through WhatsApp's recovery process. A closer look at the same subject appears in WhatsApp Usernames Raise New Identity Theft Concerns.

As with any security feature, use a PIN that's hard to guess but easy for you to remember. Avoid sharing it publicly.
