Your White Phone keeps your keys
— and keeps them there.
Every private key, every signature, every message — on hardware you hold, not a laptop that could be compromised.

The problem when others say "trust us"
Most wallets, password managers, and messaging apps ask you to trust a company's server with material that, if it's leaked, breached, or subpoenaed, is gone for good. Custodial key storage, cloud key escrow, phone-number-linked messaging accounts — every one of these is a promise, not a guarantee.
White Phone removes the promise: your keys are generated and stay on a separate device — your White Phone — never on the computer you're actually using for sensitive information. There's no server that could leak them, because there's nothing on your desktop to leak.
How it works
Your identity and credentials can now be consolidated into a single cryptographic keypair.
KeyMaster shields your valuable devices during signing, messaging, and wallet operations.
KeyMaster — SSH, GPG, Nostr signing
- Your SSH, GPG, and Nostr private keys are generated on the phone and stay there.
- Requests route over a relay running on your own machine to the phone, encrypted end-to-end.
- You approve or deny each request with a tap — a compromised desktop can't sign anything without your approval.
- Bridges standard ssh-agent and gpg-agent sockets, so tools that already talk to those agents keep working unchanged.
KeyMaster — secured messaging
- Get your White Phone, then follow our guide on how to install White Noise with our automatic KeyMaster login — on the device you want to secure.
- Once paired, your identity key never touches that device, in the intended pairing flow.
- No central server. Messages travel over Nostr, never sitting in a company database.
KeyMaster — crypto signing
- We're building wallet support on the same principle: your signing key stays on the phone.
- A compromised laptop can't move your funds without your phone's approval.

The hardware
White Phone runs on durable, off-the-shelf 5G Android hardware — chosen for daily-carry practicality, not because it's exotic. The security model doesn't depend on custom silicon; it depends on what's installed on top.
Verify it yourself
We'd rather you check than take our word for it.
- Open source. Read the code, build it yourself, or have someone you trust review it.
- No backdoor. There's no remote access point to put one in — keys and messages never reach a server we operate.
- No recovery. This is a deliberate design constraint, not an oversight — see the FAQ below.
Who it's for

FAQ
Can I buy a phone now?
The product is still under development and we currently have no units for sale. Join the waitlist and we'll contact you with information once we open for orders, including pricing and expected lead time.
What happens if I lose the phone?
You lose what's on it — the same way you would with a hardware wallet or a security key. That's the trade-off behind "no recovery": nothing recoverable also means nothing stealable from a server. Back up your seed phrase and vault backup separately, the same way you would with any hardware key.
Do you hold a backdoor or recovery key?
No. Nothing is recoverable by anyone but you — and nobody, including us, can be forced to hand over what we never had in the first place.
Can I use it with my existing SSH/GPG setup?
Yes. KeyMaster bridges standard ssh-agent and gpg-agent sockets, so tools that already talk to those agents keep working without changes.
How do I get set up?
KeyMaster comes pre-installed and ready to go on your phone. For the desktop side, every White Phone ships with a step-by-step guide covering how to download and install White Noise on whichever device you want to secure, then pair it with KeyMaster on your phone. Once paired, White Noise logs in automatically — no separate account to create, no password to manage on the desktop, nothing extra to configure. From there, your chat is up and running.
What if I just download White Noise on its own, without a White Phone?
White Noise is open source, so you're free to run it standalone. But without KeyMaster pairing, it falls back to storing your identity key in a local, password-encrypted vault on that device — solid protection at rest, but not the same guarantee as the White Phone setup, where your key never touches the desktop at all, encrypted or not. The security we advertise is the paired setup, not the standalone app on its own.
What if I'm buying for a team, not myself?
Use the enterprise option in the request form below, or reach out directly — companies typically buy through procurement rather than a one-off order, and we're set up to work that way.
