Scattered secrets are hard to keep track of

A code in a drawer, a phrase in a screenshot, a password in an old email. Every hiding place is one more thing to remember and one more thing to leak.

MI8OS holds them in one vault, encrypted on your phone and written to three cards.

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

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.
