Better than a sticky note

A sticky note under your keyboard is not encryption

You made a strong password, then gave it the weakest hiding place in the room. MI8OS keeps it encrypted on a card in your wallet.

A strong password, a weak hiding place

The password itself might take years to guess. The sticky note takes one second to read.

How it works

Write it once. Open it with a tap.

  1. 01

    Add your secrets

    Passwords, recovery phrases and private notes.

  2. 02

    Choose a Vault Password

    Only you know it. MI8OS never keeps a copy.

  3. 03

    Encrypted on your phone

    Before anything reaches the card.

  4. 04

    Tap your card

    Hold it to your phone and the vault is saved.

Who can open it

A found card is not enough

  • Your MI8OS Card
  • The MI8OS app on an NFC phone
  • Your Vault Password

Opening the vault takes all three. Nobody can recover a forgotten Vault Password, not even MI8OS.

FAQ

Before you buy

Someone finds a card I lost.

They have an unlabelled card containing encrypted data. There is nothing on it that identifies you or the vault.

I lose my phone.

Install MI8OS on another compatible phone, tap any card and enter the vault password to restore access.

I forget my vault password.

The vault cannot be reset or recovered. There is no reset option, recovery code or hidden way around the password.

MI8OS as a company disappears.

Your cards do not depend on an account or MI8OS server to hold their data.

Does the card need charging?

No. It has no battery and is powered by your phone during a tap.

Which phones work?

An iPhone or Android phone with the MI8OS app and a working contactless reader.
