Passkeys and your wallet

Why Motive 8 uses passkeys

Your Hearts are worth protecting, so Motive 8 has no passwords to steal or guess. You sign in with a passkey — your face, fingerprint or device PIN, kept by your device or your password manager.

A passkey only works on the real Motive 8, so it can't be phished. A passkey is required to open your wallet.

Your wallet key is yours, not ours

Each of your passkeys locks its own copy of your wallet key. Motive 8 keeps those locked copies, but can't open them: we have no way to sign in as you, move your Hearts or unlock your wallet.

That also means we can't open it for you. Keep your passkeys safe, and keep more than one way in.

Passkey managers that work with Motive 8

A passkey for Motive 8 has one extra job: it hands back the key that opens your wallet. Not every passkey manager can do that yet. These have been tested with Motive 8:

  • iPhone
    • Apple Passwords (iCloud Keychain)
    • 1Password
  • Android phone or tablet
    • Google Password Manager — what Chrome offers
  • Windows PC
    • Windows Hello (needs the February 2026 Windows update)
    • Google Password Manager, in Chrome
    • 1Password's browser extension — in Chrome, Edge or Firefox

Known not to work yet: Bitwarden · Microsoft Authenticator · 1Password through the Windows Security window (use 1Password's browser extension instead).

Using something else? Try it. If it can't protect your wallet, Motive 8 tells you when you make the passkey — and nothing is lost.

How to set up passkeys on your device

Keep more than one way in

  • Add another device — in Settings, choose Sign in on another device, then My phone or tablet, or My computer.
  • Heart Backup — a Restore link emailed to you. With it you can get your wallet back if you lose every passkey.
  • Your 24 words — in Settings → Heart Backup. They are your wallet itself, written down: keep them somewhere safe and private.

On a public or shared computer

On a computer that isn't yours — a library's, a hotel's, a friend's — sign in once. Nothing is saved on it.

  1. On your phone: Settings → Sign in on another device → A device that isn't mine.
  2. On the computer: open app.mv8.life/connect, type the code, check the number matches, then approve on your phone.
  3. You're signed in for up to an hour. Nothing is saved on the computer — no passkey and no wallet key.
  4. When you're done, choose Sign out. Closing the browser signs you out too.
  5. Never make a passkey on a computer you don't own. If the browser or a password manager offers to save one, say no.
  6. Forgot to sign out? It ends by itself within the hour.

While signed in once, passkeys, Heart Backup, your email and phone, and closing your account can only be changed on a device with your passkey.

If something goes wrong

  • “The passkey wasn’t saved.”You may have cancelled — or your password manager couldn't save it because it already holds an old Motive 8 passkey for this email (1Password does this). Delete the old one in your password manager, then try again.
  • “One more step”Your password manager made the passkey but didn't hand over what protects your wallet, so we ask for the same passkey once more. If it still can't, we don't keep it — choose a manager from the list above.
  • “Your passkey worked, but your password manager didn’t hand over what opens your wallet.”Your password manager signed you in but kept back the wallet key. With 1Password on Windows, use its browser extension rather than the Windows Security window. Or use another passkey on your account.
  • “That passkey manager can’t protect your wallet.” or “Your device couldn’t create the passkey.”No passkey could be made that protects your wallet. Set up passkeys on this device, or choose a manager from the list above.
  • You deleted or replaced a passkey in your password managerYour password manager doesn't tell us. Remove the old one in Settings → Passkeys too, so it stops being listed. Its “Last used” time helps you tell which one it is.
  • Your passkey is on another deviceOn the sign-in page, choose Sign in another way → Use another device. On a computer that isn't yours, see On a public or shared computer.
  • You’ve lost every passkeyOn the sign-in page, choose Lost your passkey?
