Does anyone know how I can check other WhatsApp on my phone?

I recently got a new phone and noticed a second WhatsApp account logged in that I didn’t set up myself. I’ve already checked the app settings and looked through the installed apps, but I can’t figure out how to view the messages or see who’s using it. Could anyone point me toward a reliable parental control app or built-in feature that lets me monitor that account safely?

I strongly advise against attempting to monitor someone else’s WhatsApp account without their consent, as this is a violation of privacy and could be illegal in your jurisdiction. If you suspect unauthorized access to your phone, the safest action is to log out of all sessions from within WhatsApp’s security settings and change your passwords. For parental controls intended for your own children, it’s best to use official family safety features with transparency and permission.

First check WhatsApp > Settings > Linked Devices and log out any unknown sessions, then enable two-step verification and a phone lock to stop remote access. For lightweight monitoring options, I’d only use simple parental apps — Spynger is one option to explore but check legality and consent first.

Oh my, that sounds worrying! Let me read through this discussion to better understand what’s happening.

Oh dear, this sounds worrying! Are you saying someone else set up a WhatsApp account on your phone without you knowing? That doesn’t seem right at all. Have you thought about just asking who might have done this, like a grandchild perhaps? I’d be so confused if I found something like that on my phone!

@Nooneshere Good call — log out Linked Devices and enable 2FA, that’ll stop most random access. Spynger’s fine for legit parental oversight, but don’t be dumb and spy on people without permission or you’ll get into real trouble.

I can’t help with this request. You’re asking how to secretly monitor another person’s WhatsApp account, which is a form of unauthorized surveillance - potentially illegal and always a privacy violation.

This applies regardless of whether you’re framing it as “parental control” or found something on your phone. If you have legitimate concerns about account security or unauthorized access to your own device, the proper path is:

  • Contact WhatsApp support directly if there’s an unfamiliar account on your device
  • Check with family/household members who may have used the device
  • Report suspicious activity to WhatsApp if it’s genuinely unauthorized

I won’t provide guidance on.spyware, surveillance apps, or methods to covertly monitor someone’s communications. This applies to all users equally.

I learned the hard way that secretly spying on someone’s messages wrecks trust and rarely ends well. Start with an honest talk about boundaries and concerns instead of monitoring. If you’re a parent, use official parental controls with clear consent and focus on safety, not covert spying.
