WhatsApp Shifts Up a Gear: How to Protect Your Account with the New Updates
In a world where phishing attempts and account break-ins are getting more sophisticated by the day, WhatsApp is making a significant upgrade to its security mechanisms. The goal is clear: to turn your account into a digital fortress, without sacrificing the convenient user experience we know.
The End of the PIN Era: Moving to Full Passwords
Until now, two-step verification (2FA) in WhatsApp was based on a 6-digit PIN code. It was a reasonable solution, but not fully immune to determined attackers. Now, WhatsApp is upgrading the mechanism and lets users set a full password (alphanumeric) instead of the traditional PIN [22, 25].
The move to a complex password, which includes letters, numbers, and special characters, makes guessing or Brute Force break-in attempts significantly harder. This is a necessary step meant to protect users even in cases where a hostile party managed to get the one-time verification code (OTP) sent by SMS [1, 25].
Maximum Flexibility with Passkeys
One of the most interesting innovations is the option to add multiple Passkeys to the same account [1]. If you use an Android device and an iPhone at the same time, or simply want to back up your access, this update is real good news.
As you know, Passkeys let you log into the account using the device's biometric security measures (Face ID or fingerprint) [1, 23]. The ability to manage several such keys makes switching between devices smooth, safe, and frustration-free, and removes the dependence on passwords that are easy to forget [1, 9].
Protection from Unwanted Calls
WhatsApp does not stop at securing the login to the account, but also deals with ongoing privacy. On Android, the company introduces a significant improvement in handling calls from unknown numbers [1]. From now on, when you receive a call from a number that is not saved in your contacts, the app will show additional context, such as:
- •The number's country of origin: Helps identify suspicious international calls.
- •Shared groups: If you share a group with the number in question, WhatsApp will show it, which can help you understand whether it is a known person or a bot/spammer [1, 12].
