Tesska keeps every secret in the vault and hands out short-lived, scoped, revocable tokens instead — to teammates, contractors, scripts, and AI agents.
Drop in a password or key. The server only ever holds ciphertext — envelope encryption, or zero-knowledge so even we can’t read it.
Authorize a project, person, or agent. Narrow the scope, set a TTL, flip “callable” on. They get a token — never the secret.
Sensitive calls ping your phone for approval. Every call is logged. Kill any grant in one click — instantly, everywhere.
Let an assistant log in and act as the user with a scoped, approvable, revocable token. The secret stays in the vault; every call is logged.
Manage a wall of client accounts. Grant per-project, revoke on offboarding, audit who did what.
Let users safely connect third-party accounts without handing you raw keys.
Stop pasting the team password in chat. Broker consent and see every use.
Time-boxed, scope-limited access that expires on its own. No “please remove me” later.
Every capability below is in the product — no add-on tiers, no hidden modules.
Stop sharing accounts by sending the password. Grant consent instead — who can use it, for how long, to do exactly what.
The secret never leaves the vault. Optional zero-knowledge means the server can’t read plaintext — ever.
One-click kill switch on every grant, and a full trail of who called which credential, when.
Sensitive operations push to the owner’s phone. Unlock locally, approve or reject in a tap.
Shamir secret sharing splits the key into N shares — any M reconstruct it, and the server never holds the complete key. Built for seed phrases; shipping soon.
Every grant is scoped: token TTL caps, per-minute rate limits and platform allowlists shrink the blast radius of any single key.
Ask it to review grants, run a security checkup or freeze a credential — every change goes through a confirmation card first.
OAuth-style: your users authorize in one click and your platform gets a revocable, scope-limited per-user token — no key-pasting.
Lend access, not passwords — you never hand over your real password.
