A password cannot be looked up — it is kept as a one-way scramble, so the only way back in is to set a new one. Because that is worth doing carefully, it can only be started at the computer running this server.

1. On that Mac, open Simple Schematics from Applications while it is already running.
2. Choose Reset password in the box that appears.

That opens this page again, ready. On a server without a screen, run npm run reset-password in the app's folder instead.

Setting a new password here signs that account out everywhere. Drawings, the kit library and every other account are untouched.
