The decision
Describe the sessions, SSH keys, authenticators and recovery codes that may need review after a device is lost.
A bounded example
Contain first, then rotate or revoke using documented routes. Test only accounts and devices you control.
Documentation
Use the relevant version of Ubuntu — OpenSSH before changing a live service.
Checks before change
Keep a recovery route, work on an isolated copy when data is affected, and record observations rather than assumptions. Stop if an acceptance check fails.
Limits
Hoszen does not preinstall or operate applications, hold secrets, verify backups, promise capacity or confirm a payment or VPS delivery.
