Why Your Current Setup Is Working Against You

Most people solve the password problem the wrong way. They reuse the same password everywhere because remembering dozens of different ones is impossible. Or they use a cloud password manager – which solves the memory problem but creates a new one: now every password lives on someone else’s server, behind a single master password, in a vault that has been breached more than once across the industry.

The result is a choice between two bad options: convenience at the cost of security, or security at the cost of sanity.

Seedkeeper removes that choice entirely. Your passwords live inside a certified chip in a card or ring you already carry – generated strong, stored offline, retrieved with a tap. No cloud to breach. No master password to forget.

No monthly bill for the privilege of protecting your own data.

How Seedkeeper Makes Passwords Effortless

Generate a Strong Password in One Tap

Creating a new account somewhere? Open the app, tap your card or ring and generate a password. Seedkeeper creates a unique, cryptographically strong password – long, random, impossible to guess – and stores it on your device in the same action. You never have to think of a password again, and you never have to remember one either.

Frequently Asked Questions

Is there a limit to how many passwords I can store?2026-07-14T15:09:25+02:00

Seedkeeper can store a significant number of credentials on a single device  (up to 100) – enough to cover the typical digital footprint of an individual or small team.
The exact capacity depends on the size of each stored entry. For most users, running out of storage space is not a practical concern. If you have specific requirements around credential volume, contact us and we can advise.

Can I import my existing passwords?2026-07-14T15:08:29+02:00

Yes. If you currently use a cloud password manager, you can export your credentials as a file and import them manually into the Seedkeeper companion app, which then stores them on your device.
The companion app guides you through this process step by step. Once migrated, your passwords live only on your Seedkeeper device – your old cloud manager can be cancelled or kept as a temporary reference during the transition.

What happens if I lose my card or ring?2026-07-14T15:07:18+02:00

A lost device cannot be accessed without your PIN – physical possession alone is not enough to read the contents.
If you have set up a backup device in advance, your full credential set can be restored via encrypted device-to-device transfer in a few taps.
Without a backup, a lost device means the passwords stored on it are not recoverable. Setting up a backup device on day one is the single most important step in getting started with Seedkeeper.

Does it work without an internet connection?2026-07-14T15:06:42+02:00

Yes – completely. Seedkeeper stores your passwords inside the device’s secure element, not on a server.
Generating a password, retrieving a login, storing a new credential – all of it happens locally on the device with no network connection required.
Your passwords are available on a plane, in a hotel, during an outage, or anywhere your signal isn’t.

One device.
Every password.

Stop remembering, start living. Always with you. Always offline.
