Seamside

No accounts

You're signed in everywhere, without ever making an account.

There's no sign-up anywhere in Seamside. Your devices hold keys that prove who you are, so a frame you open in your browser already knows it's you, and a friend opening your link doesn't need anything at all.

Why it matters

  • No passwords, no email address and no company holding your login.
  • The people you share with don't need an account either.

How it works

  • The first time you open Seamside, keys are made on your device. Those keys are who you are.
  • Each computer and browser you use becomes one of your devices. You confirm a new one by matching its mark on both screens.
  • A device proves who you are with a signature whenever it opens a space, so nothing ever asks you to log in.
  • Other people are known by their keys too. A space's member list is people, not email addresses.
  • Your keys are kept encrypted on your computer, and you can save a recovery copy.
Pairing a phone: the same mark on both screens
