For your authenticator

Your TOTP code is temporary. Its setup secret is not.

The six-digit code changes every 30 seconds. The setup secret behind it is what you need on a new phone. MI8OS keeps it encrypted on a card.

Lose the secret, lose the codes

When you set up two-factor login, the service shows a QR code or a text key once. That key is the TOTP setup secret.

Keep it in MI8OS and you can set up your authenticator again on a new phone. Keep it encrypted, because anyone with it can make your codes.

FAQ

Before you buy

Does the card make the six-digit codes?

No. The card only holds the encrypted vault. After you open it, the MI8OS app can show the codes from the stored setup secret.

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.
