Grooming and exploitation

Secret accounts, vault apps and second phones

Finsta accounts, calculator vault apps, hidden folders and second phones: why kids use them, how to spot them, and how to respond.

The short version
  • Secret accounts are common and often harmless, but secrecy also hides risky contact.
  • Vault apps disguise themselves as calculators or utilities, and some phones have built-in hidden folders.
  • Respond with curiosity rather than punishment, and focus on safety over control.

Many teens have more than one account: a public one their family sees, and a private one for close friends, sometimes called a "finsta" (fake Instagram) or "dump account". Some go further, with apps that hide photos and messages, or an old phone parents don't know about.

Why kids use them

  • Privacy from family: wanting space to be silly, emotional or themselves with friends
  • Peer culture: "everyone has a dump account"
  • Avoiding controls: getting around time limits or app restrictions
  • Hiding risky things: contact with someone they know you'd disapprove of, or images

Most secret accounts are about the first two. But secrecy is also what groomers rely on, so it's worth understanding.

Types of hidden spaces

  • Second accounts on Instagram, TikTok, X or Facebook, often under a nickname
  • Vault apps that look like a calculator, clock or file manager but open a hidden photo and message store with a code
  • Built-in hidden spaces: Samsung's Secure Folder, Android's Private Space on newer phones, hidden photo albums on iPhone
  • Second phones: an old phone, a hand-me-down from a cousin, or one bought with saved money
  • Disappearing message apps. See disappearing messages and secret chats.

Signs

  • Two versions of the same app, or apps with odd names
  • A "calculator" app that's used a lot
  • Storage full of photos you can't see in the gallery
  • Your child switching accounts when you're near
  • Device time that doesn't match what parental controls report
  • Wi-Fi connections from a device you don't recognise

How to respond

Keep perspective

A teenager wanting some private space isn't necessarily doing anything wrong. The question is whether the secret space is hiding something risky.

Talk first

"I've noticed you have a second account. I'm not upset that you want some privacy. I want to make sure you're safe. Who can see it? Who do you talk to there?"

Agree on safety basics

Even for private accounts:

  • Account set to private
  • No followers they don't know in real life
  • No sharing of revealing photos or personal details
  • They tell you if anyone makes them uncomfortable

When to look closer

If you have a specific safety concern, like signs of grooming, sextortion, self-harm or a much older contact, it's reasonable to look at the device together. Explain why. See online grooming warning signs.

Prevention

  • Children who feel they have some privacy are less likely to build elaborate secret systems.
  • Agree on what's private (messages with friends) and what's not (who they're talking to, apps they install).
  • Block the installation of vault apps for younger children using app approvals.
