What WhatsApp is
WhatsApp is the world's most-used messenger and encrypts messages end-to-end by default. Its view-once photo and video feature and disappearing-message timers make it usable for private exchanges, and nearly everyone already has it. The trade-off is that it is tied to your phone number and owned by Meta.
What WhatsApp does well
- End-to-end encryption on by default
- View-once media and disappearing-message timers
- Enormous reach, the other person almost certainly already uses it
- Free
Where it falls short
- Tied to your phone number, which you have to share
- Owned by Meta, with the metadata concerns that come with that
- Not anonymous and not built for meeting strangers
Verdict: The convenient encrypted option when you and the other person are already connected. Reach and default encryption are its strengths, sharing a phone number and Meta ownership are the costs.
