How to automatically block unknown numbers on WhatsApp iPhone

Unlike many other messaging services, WhatsApp doesn’t require a username to access the service. As an alternative method of user authentication, the platform makes use of the users’ phone numbers. People are able to identify themselves using this way.

Even though this function makes logging into the system much simpler, it is not without its drawbacks. Any random person with your phone number can use the app to find you and send you a message in complete secrecy.

Unfortunately, WhatsApp for iPhone lacks this capability, making it impossible to automatically block unwanted calls from unknown numbers. Although there is always the option to modify your WhatsApp privacy settings in case you do not wish to receive unwanted messages from a certain number, such as spam or messages that are improper.

How to maintain privacy on WhatsApp

It is only logical for us to utilize WhatsApp to communicate with our close friends and exchange information with them. After all, it is designed to facilitate communication. However, by default, WhatsApp is set to disclose a greater amount of information about you with your contacts and other users than you presumably are aware of.

This ease of use, however, is sometimes undermined by unsolicited texts from unidentified numbers, which can soon become a source of annoyance.

If you want to keep your profile and chats hidden on WhatsApp, you should enable these safety settings right now.

1. Manage last seen

WhatsApp contacts might see your last seen status if you haven’t turned on the privacy setting. Let us inform you that many scammers check random numbers’ last seen to determine whether the contact is active or not, so be aware that anyone with your mobile number saved in their contact list can see the last time you were live on the app.

As a result, you are required to maintain your last seen status on nobody or my contacts.

2. Private status

Status privacy is an additional level of anonymity protection. Anyone in your contact list could potentially see the photos and videos you post to your status.

You have the ability to choose who can view your “Status” updates on WhatsApp, which are short photographs or videos with text captions that are only visible for the first 24 hours and then disappear. It is imperative that you restrict access to the status privacy settings to only your contacts.

3. Enable two-step verification

Setting up two-factor authentication is another great way to prevent unauthorized users from accessing your WhatsApp and reading your private messages. If you enable this security measure, you’ll be asked to enter a six-digit code in addition to your password. This makes it significantly more challenging for an outsider to access your account without your permission.

The WhatsApp account settings may be accessed by clicking the gear icon in the top right. There’s a choice for two-factor authentication there.

4. Limit my profile to contacts

You have greater control over who can see your data and interact with you thanks to the numerous privacy settings that are available to you through WhatsApp.

In the WhatsApp settings, there is a section titled “who can access my profile.” This section lets you control who can view your profile. If you have the settings to be visible to everyone, then you are most certainly putting your privacy in danger.
