Nextcloud Deck login on iPhone,
and why sign-in fails.
Most failures come from the server URL, two-factor authentication, or Deck missing on the server.

How Deckloud login works
In self-hosted mode, Deckloud uses Nextcloud's Login Flow: enter your Server URL, tap Connect, sign in on your server's own page, and tap Grant access. Deckloud then keeps its own credential in the iOS Keychain; it never sees your password and needs no Deckloud account.
02
The checklist, in order
Exact server URL.
Include https and any subpath, such as https://example.com/nextcloud. Copy it from your browser.
Deck opens in the browser.
Open Deck in Safari with the same account. If that fails, fix the server first.
Two-factor accounts: use an app password.
Create one in Nextcloud under Personal settings, Security, Devices & sessions. On the login page, choose Alternative log in using app password.
Finish the browser step.
Sign-in ends when you tap Grant access. Closing the browser earlier leaves Deckloud waiting.
03
After login: if boards are missing
An empty board list after login means Deck is disabled, the account has no boards, or you chose another account or server. The troubleshooting guide covers it.
FAQ
Practical questions
Is entering my password in the Login Flow safe?
Yes. You type it on your own server's page, and Deckloud only receives a device credential that you can revoke in Nextcloud's security settings.
Can I sign out of one server and into another?
Yes. Accounts are per server, switching leaves both servers' data alone, and two saved accounts are free.
Why does my home server log in on Wi-Fi but not on cellular?
The hostname probably resolves only inside your network, through local DNS or a VPN. Make the server reachable from the internet, or connect your VPN first.
