Signal: the parent’s guide
End-to-end encryption is the feature and the challenge. Here’s the nuanced take.
What Signal is
Signal is end-to-end encrypted messaging, widely trusted by journalists and privacy advocates. It’s clean, minimal, and ad-free.
Why teens use it
- Privacy-minded friend groups.
- Disappearing messages by default.
- No ads, no algorithms, no shared metadata.
Why it’s tricky for parents
- True end-to-end encryption. No monitoring tool can read Signal messages. Content-alerting software like Bark can’t see into Signal at all.
- Disappearing messages erase evidence if your kid needs to report bullying, sextortion, or threats.
- Phone number-based — your kid’s Signal username is tied to their phone number by default.
Settings that matter
- Privacy › Phone number › Nobody (hide from search).
- Privacy › Who can find me by number — Nobody or My Contacts.
- Privacy › Registration lock — on (prevents SIM-swap account theft).
- Privacy › Read receipts — user preference.
- Set disappearing messages to a reasonable default (1 day, 1 week) — but teach your kid: if bullying or threats happen, TURN DISAPPEARING MESSAGES OFF, screenshot, then come to you.
The parent conversation
Signal itself isn’t the problem — it’s a better-designed messenger than most. The conversation to have with a Signal-using teen is: if something bad happens in Signal, you can’t rely on tools to surface it. You need them to tell you.
When to worry
Sudden adoption of Signal after avoiding it — especially paired with disappearing messages — often indicates the teen is hiding a specific conversation. Worth a non-confrontational check-in.
