Connect the server in Fodide

First set up Cloudflare: the server is reached through your tunnel. Then, in Fodide, Settings → Connectors → Servers → Connect a server. Fill in That login's private key, IP address, Login (root unless the provider says otherwise), A short name and Your domain on Cloudflare. Tap Check, then Keep on this phone.

Used once, then forgotten. Fodide logs in with it, creates its own two accounts (fodide-ops for deploys, fodide-audit for read-only checks), and discards what you typed.
