Identity you can actually recover.
Plexus is the sign-in and permissions layer beneath our software. One master identity stands behind all your keys, the permissions you hand out can be taken back, and you get your whole account back from security questions — not a seed phrase you can lose. It runs in a normal browser tab, with no extension to install.
The seed-phrase problem
For years the rule has been: write down twelve secret words, keep them safe forever, and never let anyone see them. It's a terrible deal for ordinary people.
Lose the words, lose everything
There's no reset link and no support line. A misplaced or destroyed seed phrase means the account — and whatever it holds — is gone for good.
Anyone who sees them is you
The same words that let you back in let anyone else in too. One screenshot, one phishing page, one nosy houseguest, and the account is theirs.
Permissions you can't take back
Once you've granted access to an app, clawing it back is awkward at best. Most people just hope for the best and move on.
People shouldn't have to choose between security and ever getting back in. Plexus is built so the safe way and the human way are the same way.
What Plexus gives you
One identity behind every keyderived on demand
You have a single master identity. Every key you need is worked out from it the moment it's needed, then put away again. Your private keys are never stored on a server and never sent anywhere — so there's nothing sitting around to be stolen.
Permissions you can take backrevocable
When you grant an app or a partner access, that permission is something you can cancel. Take it back and it stops working — cleanly, without re-doing your whole setup.
Recover from security questionsno seed phrase
Instead of guarding twelve secret words, you set up a few private questions. Answer them and your whole account is rebuilt from your master identity — the everyday way to get back in, made safe.
Works in any browserno extension
Plexus runs in a plain browser tab. No plugin, no app store, no extension to install or keep updated — just open the page and sign in.
How recovery works, in plain terms
Your master identity is the root
Everything you do traces back to one identity. Keys aren't a pile of secrets to keep — they're worked out from that root when needed.
Questions stand in for the words
Set a few private questions only you can answer. Together they let your account be rebuilt — without ever writing down a seed phrase.
Rebuilt, not handed over
When you recover, your identity is re-derived on your side. There's no master password stored somewhere waiting to leak.
Where it stands today — honestly
We believe in being straight about what's built and what isn't. The cryptographic foundation of Plexus is compatible with Dusk's official toolkit at the core level — the master identity, the secure handshake between two parties, and the way identities are named all line up. That's a deliberately solid base to build on. It is a compatible foundation, not a drop-in replacement — the layers above diverge by design.
Question-based recovery is the model we build on, and it works end to end in our own tests. Full cloud-backed recovery — the kind a member of the public would lean on day to day — depends on a hosted service behind it, so we describe it as our approach and design, not a finished consumer product you can sign up for today.
Built on Semantos
Plexus is the identity and permissions layer for Semantos, our shared layer that sits beneath your apps. It's how a Semantos app knows who you are and what you're allowed to do — the same identity following you across every app and every role you play.
