Manifesto / 01
Our mission
Secrets belong to people,
not platforms.
Digital ownership should not depend on a company keeping your account alive. Meta Secret builds open-source cryptographic systems where authority begins on devices you control and access is shared only by deliberate consent.
Storage can be replaced. Infrastructure can disappear. Your ability to prove who you are—and recover what is yours—should survive both.
Protocol / 02
Design constraints
We remove the
single point of trust.
Device controlled
Authority lives with approved devices and cryptographic identities—not a central account database.
Ciphertext outside
Secrets are encrypted before leaving the client. Storage providers carry data without owning access.
Consent required
New participants and sensitive operations require visible, deliberate authorization.
Open machinery
Security deserves inspection. The code, protocols, and trade-offs are built in the open.
01 / Advanced system
No participant holds
the whole secret.
ID0 is the advanced Meta Secret implementation: a decentralized password manager built around secret sharing, biometric device access, and encrypted storage across independent participants.
02 / Lightweight system
Keys, not accounts.
Nook is a local-first password and secrets manager. Choose the vault that matches the trust model you need; both keep cryptographic authority under your control.
Horizon / 03
Our vision
A future where losing a platform does not mean losing yourself.
Portable identity. Replaceable storage. Deliberate trust. Personal infrastructure that remains useful when a service, company, or network disappears.
