TRANSPARENCY IS A FEATURE
Trust the code.
Know the limits.
Clear security behavior, explicit warnings and publicly reviewable source. We would rather explain the real trade-offs than hide them behind marketing.
Saved credentials are not encrypted.
BetterTTY currently uses secrets.mode = plain-v1. Saved passwords and private-key contents can be stored as human-readable values in BetterTTY.json, its backups and exported configurations. There is no built-in encrypted credential vault or master password in version 1.0.2.
Use BetterTTY only on trusted machines, protect the files with operating-system permissions, and never post private configurations, SSH keys or logs publicly.

Verify before authenticating.
Authentication doesn't mean blindly trusting whoever answers on a port. BetterTTY verifies a server's host key and asks you to make deliberate trust decisions.
Unknown host
Review the host-key fingerprint against an independent trusted source before trusting it.
Changed key
A changed host key must not be silently accepted. Investigate unexpected changes before reconnecting.
Portable trust records
Trusted known-host records can support multiple valid algorithms for the same host and port.
PRACTICAL PRECAUTIONS
Keep your environment private.
✓ Do
- Use an OS account and device you trust.
- Protect BetterTTY.json and every backup/export.
- Verify host-key fingerprints out of band.
- Review diagnostic logs before sharing.
- Back up remote files before overwriting them.
- Verify release origin and SHA-256 checksums.
✕ Don't
- Assume passwords or private keys are encrypted at rest.
- Commit real configs to GitHub.
- Accept unexpected SSH fingerprint changes without investigation.
- Rely on SFTP upload overwrite atomicity.
- Assume disabled logging means zero operational data exists elsewhere.
- Treat an exported config as a sanitized sessions-only bundle.
CURRENT PRODUCT LIMITS
What 1.0.2 doesn't do.
Some features are intentionally conservative or planned for the future. They are not silently advertised as shipping today.
Security & credentials
- No master password or encrypted at-rest credential vault.
- Exported configuration and backups can contain plaintext secrets.
- No automatic sanitizing of shared configuration files.
- Diagnostic metadata can contain host, user and path identifiers.
Terminal & management
- Multi-Exec is a placeholder only, not command broadcasting.
- Session traffic is not OS-wide network monitoring.
SFTP transfers
- No folder synchronization or mirroring.
- No transfer resume or parallel transfers.
- No recursive delete for non-empty directories.
- No rename, chmod/chown or metadata preservation.
- No symlink following during recursive folder transfer.
- Remote overwrites are not atomic.
Distribution
- No claim of Apple notarization unless a specific release is notarized.
- The listed Mac package is Intel x86_64, not universal.
An interrupted upload may leave a partial remote target. In particular, replacing an existing remote file is not guaranteed crash-safe. Back up important remote targets first.
OPEN SOURCE
Inspect. Question. Improve.
Security work benefits from scrutiny. Read the source, review a relevant document, or report a reproducible bug through GitHub.
Please do not post real credentials, private keys, or sensitive infrastructure identifiers in public issues.
