Beautifully Crafted. Relentlessly Secure.
Seedkeeper PRO Ring is made from matte black ceramic – a material harder than steel, resistant to scratches, and completely hypoallergenic. The finish is deliberate: matte reads as considered, not shiny. Permanent, not flashy. The kind of object that ages well on your finger rather than showing every mark.
The Seedkeeper logo is engraved on the inside of the ring – invisible when worn, present when it matters. A detail for the person wearing it, not for anyone else.
This is what security looks like when it’s designed to be worn.
Three Things You Carry.
One Ring That Replaces All of Them.

Your Password Manager
Every password you’ve ever created, stored offline inside a certified secure element on your finger. Generated strong, stored safe, retrieved with a tap. No monthly subscription. No server that can be breached. No master password to forget.

Your Security Key
FIDO2 Level 1 certified passkey authentication; tap your ring to log into any supported website or app without typing a password at all. Phishing-resistant by design. The same standard used by Apple, Google, and Microsoft, on hardware you can independently verify.

Your Authenticator App
Offline TOTP code generation with no network dependency, no phone signal required, no authenticator app to lose when you change devices. Your 2FA codes are generated inside the ring itself, available anywhere, always.
Everything On Your Finger
FIDO2 passkey login
Tap your ring to log into any FIDO2-supported website or app: no password required, phishing-resistant by design, bound to the legitimate site’s domain.
Password generation and storage
Generates and stores unique, strong passwords for every account, offline, inside the ring’s EAL6+ certified secure element, accessible only with your PIN.
Offline 2FA code generation
TOTP codes generated locally inside the ring – no authenticator app, no phone signal, no network dependency, no single point of failure.
Complete credential storage
Passwords, recovery phrases, sensitive notes – everything that matters, stored safely offline on your finger.
Matte black ceramic
Harder than steel, scratch-resistant, hypoallergenic. Designed to be worn every day, for years. The Seedkeeper logo engraved inside – a detail for the wearer, not the audience.
100% open-source
Firmware and companion app published in full on GitHub, independently auditable, no black box, no hidden server-side logic.
Which Format Is Right For You?
Both PRO formats carry identical security credentials: same EAL6+ certified secure element, same FIDO2 Level 1 certification,
same password manager, same offline TOTP generator.
The choice is entirely about form factor and how you want to carry your security.
