How It Works
- First connection to a host prompts for trust
- Accepted host fingerprints are stored locally
- Future key mismatches are flagged and require review
Manage Entries
From Known Hosts, you can:- review stored fingerprints
- remove outdated entries
- import entries from your SSH environment
When to Remove a Host Key
Remove an entry only when you have verified one of these:- host was rebuilt
- host keys were rotated intentionally
- infrastructure was migrated and fingerprint changed as expected
