How it works

Three quiet ideas, working together.

01

Stays on your phone

Your ID is stored only on this device. No company holds it, no server can leak it, no account can be locked.

02

Works in every app

Sign in instantly to any supported app. One tap. No usernames, no resets, no passwords to remember.

03

You decide what to share

Apps must ask before seeing anything. You approve each request, one field at a time, every time.

Privacy by design

No email. No server. No middleman.

Your recovery phrase is the only way back in, so we built Mycelia to give you full custody and full responsibility. The trade-off is honest, and the trade is yours to make.

  • Recovery phrase generated on device, never transmitted
  • Per-app, per-field consent every time a request is made
  • Open spec. Any developer can integrate Mycelia sign-in

The honest part

Your recovery phrase is the only way back in.

When you create your Mycelia ID, you get a twelve-word recovery phrase. It's generated on your phone and never leaves it, which means no one, not even us, can see it or reset it for you.

That's the deal with an identity no company holds: there's no support line that can let you back in if it's gone. Write your phrase down, keep it somewhere safe, and treat it like the key to your home. The responsibility is yours, and so is the control.

Questions

The things people ask first.

What does "your identity on your phone" actually mean?
Your ID is created and stored on your device, not in an account on our servers, not in a profile in some database. You hold it, you carry it, and you decide who gets to see it.
Do I need to know anything about crypto or blockchain?
No. Underneath, your ID is secured on the BSV blockchain, but Mycelia handles all of that quietly in the background. You'll see the apps you can sign in to and the requests you can approve, never wallet addresses or jargon.
What happens if I lose my phone?
As long as you have your twelve-word recovery phrase, you can restore your ID on a new device in under a minute. Without it, the ID can't be recovered. See The honest part above.
Who can see my data?
Only you, and only the specific details you approve, one request at a time. Apps must ask before they see anything, every single time. Nothing is shared by default.
What does it cost?
Mycelia is free to download and free to use. There's no subscription and no account to pay for.
Who's behind Mycelia?
Mycelia is a project of the Bionutrient Food Association, built on an open spec so any developer can add Mycelia sign-in to their app.
