Too Many Passwords to Remember

How are you supposed to remember 67 different passwords?

Most people end up using the same one everywhere – or writing them on a sticky note. Seedkeeper Classic generates a strong, unique password for every account and remembers all of them for you. You just tap the card to reveal them.

Locked Out Again

“Forgot your password?” – for the fourth time this month.

Getting locked out of your email, your bank, or your favourite app is frustrating, time-wasting, and sometimes genuinely stressful. Seedkeeper Classic means you always have your passwords with you, even when your memory doesn’t.

Is My Password Manager Really Safe?

Your cloud password manager got hacked. Now what?

Several major cloud password managers have suffered breaches in recent years. When your passwords live on someone else’s server, you’re trusting their security team as much as your own. Seedkeeper Classic stores everything offline, inside a military-grade certified chip – no server, no breach risk, no one else involved.

What If I Lose Everything?

What happens to your accounts if your phone breaks tomorrow?

If your passwords live only on your phone or in an app, losing that phone means losing access to everything that depends on it. Seedkeeper Classic is a separate physical device – your passwords are safe even if your phone isn’t. A reliable backup solution for now and beyond.

Here Is How It Works

02 – Find Your Password

Open the companion app on your phone or computer. Your passwords, notes, and account details are all there — organised, searchable, and readable only by you. Find what you need in seconds.

Copy the contents of any Seedkeeper device onto any other, regardless of tier or form factor: card to card, ring to card, PRO to Classic, Classic to PRO. The backup process takes only a few taps and uses encrypted device-to-device communication – your secrets never leave the secure element unencrypted during the transfer.

Classic as backup. PRO as daily driver. Full peace of mind.

What’s Inside the Card

Frequently Asked Questions

What is the difference between Classic and PRO?2026-07-09T14:36:19+02:00

Seedkeeper Classic and PRO use the same certified secure element and the same physical card format. The difference is two additional functions in PRO: FIDO2 passkey login (tap to log into websites without a password at all) and offline TOTP code generation (2FA codes without an authenticator app). If you mainly want to generate and store strong passwords and never want to forget a login again, Classic does that perfectly at a good price. If you also want to replace your authenticator app and log into websites with a tap rather than a password, PRO adds those two functions for an extra cost.

Is my data stored online anywhere?2026-07-09T14:35:20+02:00

No. Seedkeeper Classic stores everything inside the card’s certified secure element – your passwords, notes, and recovery phrases never leave the card unencrypted and are never transmitted to any server, cloud service, or third party.
There is no account to create, no subscription to manage, and no online service that could be breached or go offline. Your data exists in one place: the card in your hand.

Does it work with my phone?2026-07-09T14:34:46+02:00

Yes. Seedkeeper Classic works with any NFC-enabled smartphone  – iOS and Android – via the free companion app.
It also works with any standard ISO/IEC 7816 smartcard reader connected to a desktop or laptop computer, giving you two ways to access your passwords without any cable or wireless pairing required.

What happens if I lose my card?2026-07-09T14:34:04+02:00

If you’ve set up a backup device – which we strongly recommend doing after the first setup –  your passwords can be fully restored to a replacement card via encrypted device-to-device transfer.
Without a backup, a lost card means the passwords stored on it are not recoverable. This is why setting up a backup card on day one is the single most important step in the setup process.
A Seedkeeper Classic card makes an ideal backup for another Classic or for a Seedkeeper PRO device.

Do I need to be technical to use Seedkeeper Classic?2026-07-09T14:33:12+02:00

Not at all. Seedkeeper Classic is designed for everyday use – setup takes less than a minute using the companion app, which guides you through every step.
You don’t need to know anything about encryption, secure elements, or cybersecurity to use it. If you can tap a bank card on a payment terminal, you can use Seedkeeper Classic.
