Everything You Need to Know

How does Seedkeeper PRO prevent phishing attacks?2026-10-05T22:47:07+02:00

Seedkeeper PRO uses FIDO2 passkey authentication, which is cryptographically bound to the exact domain of the legitimate service.

When you tap to log into Google, your device signs a challenge specifically from google.com – a fake login page on a different domain cannot generate that challenge, and therefore cannot trigger authentication.

Even the most convincing phishing page is invisible to the authentication process. This is what phishing-resistant means in practice: not harder to phish, impossible to phish by design.

Is Seedkeeper PRO compliant with GDPR?2026-10-05T22:47:38+02:00

Yes, Seedkeeper PRO is fully GDPR compliant. This is reinforced by design: the device requires no account, no login, and collects no personal data during normal operation.

With no centralized database of user information, there is structurally very little personal data for GDPR to regulate in the first place.

What is digital sovereignty?2026-10-05T22:46:48+02:00

Digital sovereignty is the principle that individuals should have full control over their own digital data, credentials, and access – without depending on third-party platforms, cloud providers, or external services to manage, store, or secure that information on their behalf.

In practice, it means choosing tools that keep your data under your direct control, that operate transparently, and that do not create dependencies on companies whose interests may not align with yours.

What is TOTP and why is it better than SMS codes?2026-10-05T22:47:13+02:00

TOTP stands for Time-based One-Time Password – a six-digit code generated locally on your device using a shared secret and the current time.

Unlike SMS codes, which travel over the cellular network and can be intercepted via SIM-swapping attacks, TOTP codes are generated entirely offline with no network transmission involved.

Seedkeeper PRO generates these codes inside the device’s secure element – meaning the secret behind your codes never touches your phone’s operating system or any external server.

What does open-source actually mean for my security?2026-10-05T22:47:32+02:00

Open-source means the complete code – firmware running inside the secure element, and the companion app on your phone or computer – is publicly published and independently auditable by anyone.

You don’t have to take our word for how Seedkeeper PRO handles your credentials: you can read exactly what happens to your data, or have a security professional review it on your behalf.

For a device that holds your most sensitive digital secrets, verifiable transparency is a stronger security guarantee than a closed-source promise.

What is a passkey and how is it different from a password?2026-10-05T22:47:25+02:00

A password is a shared secret – you create it, you type it, and a server stores a version of it.

Every time you log in, that secret travels across the internet in some form, which means it can be stolen, guessed, or leaked in a data breach.

A passkey works differently: your device generates a unique cryptographic key pair – a private key that never leaves your device, and a public key stored by the website.

Login happens by proving you hold the private key, with nothing sensitive ever transmitted. There is nothing to steal, nothing to guess, and nothing to leak.
