SFTP & SSH

SFTP (file transfer over SSH) is the way to upload a site in bulk. Plain FTP is not offered.

Connecting

Protocol	SFTP
Host	the server hostname, e.g. `panel.hoster.example`
Port	22
Username	your account name
Password	your panel password (or an SSH key)

Works with FileZilla, WinSCP, Cyberduck, Transmit, or the sftp command. You land in your home directory; put website files in public_html/ (primary domain) or the domain's folder.

Access modes

The SSH / SFTP page has three modes:

SFTP only (default) — file transfer only, no shell.
Shell + SFTP — a full bash login for command-line work (ssh acme@panel.hoster.example), e.g. running Composer, WP-CLI or database imports with mariadb. Cron jobs are still managed through the panel; crontab -e is disabled.
Off — no SSH or SFTP access at all.

SSH keys

Add public keys (ed25519, ECDSA, or RSA of at least 3072 bits) on the page; each gets a name and shows its fingerprint. Keys are written to ~/.ssh/authorized_keys by the server — edit them through the panel, not by hand, or they will be overwritten.

Once a key works, you can disable password login for your account so only keys are accepted. The panel refuses to disable it while you have no keys.

Notes

Everything you upload is owned by your own user; PHP runs as the same user, so no permission fixing is needed. Sensible modes are 644 for files and 755 for directories.
SFTP users are not "jailed" to their home, but every other account's home is unreadable to you and yours to them.
A suspended account loses SSH/SFTP access until it is unsuspended.
