I’ve been using Termius for a few years for an SSH client. Have have a lot of self-hosted servers both in my home lab and on VPSs. I’m looking to cut some costs since it’s $120/year and really the main thing I use it for is syncing my SSH accounts and credentials between a laptop, a desktop, and my Android phone. So I’m looking for a new method to sync these things.
I’d prefer a single application, but I’d settle for a good, secure way to sync the credentials and recommendations for applications on Fedora and Android.
Edit: I’m OK with a one time payment application, but prefer open source or a solution I can self-host the sync server. And I don’t want a subscription.
Not an answer, but I’m curious: what’s wrong with just having several ssh keys, one per device?
The primary issue is I don’t always access devices from only those 3 systems. If I’m traveling or I wipe my device or get a new one, I would have to add the new key to many servers as authorized keys, and I’d need to have password access enabled in order to add the keys in the first place. Also, I want a key backed up in case of disaster since all of my devices are in my home most of the time. A few people use these systems, but only I maintain them.
You can back up ~/.ssh though, and restore it on any system.
In fact, that’s generally what you want to do, since if one device gets lost or compromised, you just revoke access to the key for that device.
