What is Signal?
Signal is a non-profit end-to-end-encrypted messenger. Strong privacy, used by journalists, activists, and increasingly teens.
How does Signal work?
Sign up with a phone number (or now a username), message contacts. Disappearing messages are standard. No server-side message storage.
What parents need to know
- Server-side moderation is impossible by design — Signal can't see message content.
- Disappearing messages are a feature, not a bug.
- Teens use Signal specifically to avoid parental visibility.
- Group invites can come from anyone who has your number/username.
Serious risks & safety concerns
Designed to be unmonitorable
Most parent-control tools can't see Signal content. Endpoint monitoring (on the device itself) is the only way.
Disappearing messages
Sexting and risky conversations leave no record on Signal by design.
Parental controls available
Signal has no parent-control features. The product cannot include them without breaking the encryption model.
How MyParentalControls covers Signal
MyParentalControls reads Signal conversations on your child's PC — end-to-end encryption doesn't prevent endpoint monitoring on the device itself.
Bottom line
High school and up, with the parent conversation that this is the platform with the most privacy.
