Support

Most questions are answered in the step-by-step guides and the FAQ. The troubleshooting table explains every connection message DuoShell shows.

Contact us

Email support@duoshell.link. We read every message.

To help us help you quickly, include:

Your device (for example iPhone 16 or iPad Air) and its iOS or iPadOS version
DuoShell's version (in the TestFlight app, or Settings → Apps → DuoShell)
What kind of server you're connecting to (Mac, Ubuntu, Raspberry Pi…)
The exact message DuoShell shows, and what you tried

Never send us a password or a private key. We'll never ask for one. Public keys (lines starting with ecdsa-sha2-nistp256 or ssh-ed25519) are fine to share.

Beta testers

In the TestFlight app, open DuoShell and tap Send Beta Feedback, or take a screenshot while using DuoShell and share it as feedback.
