Messenger Encrypted Chats

End-to-end encryption means only the people in a chat can read it. Secure storage keeps an encrypted backup so your history can follow you to new devices.

How Encrypted Chats Work

Meta is moving personal Messenger chats to end-to-end encryption by default. Messages and calls in those chats can be read only by the people in them, not even by Meta, unless someone reports a message. Some chats, such as those with businesses or on Marketplace, don't currently support it.

Secure Storage PIN

The PIN that unlocks your encrypted backup

You create this PIN when you turn on secure storage. Enter it on a new device to bring back your end-to-end encrypted chats.

One-Time Code

Restore with a code from your phone

If you forget the PIN, a one-time code can be sent to Messenger on a mobile device where you've used it recently. Never share that code.

Logged-in Devices

See which devices hold your encrypted chats

Open your encrypted chat settings and review the logged-in devices list. Log out any device you don't recognize, then change your password. Menu names may vary by app version.

See How It Works
Secure Storage
When you log in on a new device, encrypted chat history doesn't appear on its own. You restore it from secure storage with the method you chose: the PIN you created when you turned secure storage on, your Apple account on iPhone, a Google account on Android, a one-time code sent to Messenger on another device where you used it recently, or a 40-character code. Some options are still rolling out.
Forgot PIN
Messenger can't reset your PIN or restore your backup for you. You can reset the PIN only on a device where you created it or entered it before, so do that while you're still logged in there. If no such device is left, use another restore method you set up, such as a one-time code or the 40-character code. Without any of them, older encrypted history may not come back on the new device.

What Encryption Does Not Cover

1

Reports

If someone in a chat reports messages, those messages are shared with Meta for review. Encryption protects content in transit, not from the people in the chat.
2

Forwarding

Anyone in the chat can forward, screenshot or copy what you send. Encryption doesn't control what the other person does with a message once they can read it.
3

Meta AI Chats

Messages you send to Meta AI can be accessed by Meta as described in its Privacy Policy and Meta AI terms. Don't share private details there expecting encryption to cover them.
4

Your Own Device

Encryption doesn't stop someone who has your unlocked phone or logged-in account. Check which devices are logged in to your encrypted chats and log out any you don't know.

Tips for Keeping Encrypted Chats Safe

  • Pick a PIN

    Choose a PIN only you know and can recall

    Your secure storage PIN unlocks your encrypted chat backup. Avoid birthdays and your phone unlock code, and store it somewhere safe outside Messenger so a new phone doesn't leave you stuck.

  • Two methods

    Set up more than one restore method

    A PIN is easy to forget. Where available, add another restore option such as your Apple or Google account, so losing one method doesn't cost you your chat history on a new device.

  • Verify keys

    Compare keys in chats that need extra trust

    Messenger lets you check the keys for an encrypted chat. Comparing them with your contact helps confirm the chat is secured between your devices and theirs.

  • Device check

    Review logged-in devices regularly

    Encrypted chats are available on every device logged in to your account. Look over the logged-in devices list for encrypted chats and log out anything you don't recognize. Change your password afterward.
