WhatsApp is an app provided by Meta, the parent company of Facebook, Messenger and Instagram. Millions upon millions of users use this app, myself included. It is safe to use.

I suppose "safe" depends on whether and how far you trust Meta...

Just because millions of people use it doesn't make it "safe"...

WhatsApp has suffered numerous breaches and serious security problems resulting in leaked / stolen user account information and data in the last few years.

It may be fine for some, but I personally don't trust it or Meta.

I have never had an issue with WhatsApp. I change my password regularly and as messaging service, it works just fine.
