tshc

I built tshc because logging in to several Teleport clusters one by one got old. It reads local-login credentials from KeePass, runs tsh login, and lets you pick one cluster or sign in to all of them. TOTP can come from KeePass or from an authenticator on your phone.

tshc is for Teleport's password-and-OTP login flow. It does not automate SSO or browser-based login.

What you need

• tsh installed (in PATH, unless you set tsh_path)
• A KeePass .kdbx database with a UserName and Password in each Teleport entry
• Go 1.26.8 or newer if you use go install or build manually

fzf is optional. With it, you get a searchable cluster list. Without it, tshc shows a numbered list in the terminal.

Install

With Homebrew on macOS or Linux:

brew install kuyantus/tap/tshc

The Homebrew formula does not install Teleport: keep using the tsh version that works with your clusters. It does not install fzf either, since the built-in selector works without it. To update later, run brew upgrade kuyantus/tap/tshc.

On macOS, Homebrew directories may be writable by the admin group. To use fzf or tsh from those directories, add this top-level setting to ~/.tshc/teleports.yaml only if you trust every member of that group:

trusted_executable_groups: [admin]

This explicitly allows group write permission on parent directories owned by you or root. Executable files must still be owned by you or root and must not be writable by a group or others; directories writable by everyone remain rejected. No groups are trusted by default. If an automatically discovered fzf fails validation, tshc explains why and uses the numbered selector. An invalid explicit fzf_path still produces an error.

If you already have Go 1.26.8 or newer, you can also install with:

go install github.com/kuyantus/tshc@latest

Or build from a checkout of this repository:

go build -o tshc .

First run

Run tshc once. It creates ~/.tshc/teleports.yaml and stops so you can edit the file before any login is attempted. Your existing config is never replaced.

Here's a small example:

keepass_db: /path/to/passwords.kdbx
keepass_password:
  source: keychain

teleports:
  - name: work
    proxy: teleport.example.com
    keepass_entry: Teleport/work
    totp_source: prompt
    tsh_args:
      - --ttl=480

Replace the database path, proxy address, and KeePass entry path with your own. keepass_entry is relative to the database's root group: use group/entry, or just entry if it is in the root group. The optional tsh_args list is passed to tsh login; --ttl=480 requests 480 minutes (eight hours), subject to your Teleport cluster's limits.

On macOS, save the KeePass master password in Keychain before your next run if you want to avoid entering it each time. See Using Keychain below. On Linux, tshc asks for the password in the terminal.

Now run tshc again and choose a cluster. Select [ALL] to log in to each configured cluster in turn.

TOTP and other options

Set totp_source on each cluster:

• prompt asks for a code when tsh requests one. Use this for an authenticator on another device.
• keepass generates a code from the KeePass entry's otp field. That field must contain an otpauth://totp/... URI. This is the default if totp_source is omitted.

You can also set login_timeout (default 5m), or provide absolute tsh_path and fzf_path values if the executables are not in PATH. The generated configuration template shows the layout.

For command help and the installed version:

tshc --help
tshc --version

Using Keychain

With keepass_password.source: keychain on macOS, save your KeePass database's master password once:

tshc keychain set

Enter the KeePass master password when prompted in the terminal. It is saved in your default macOS Keychain, not in teleports.yaml.

On the next run, macOS shows a Keychain access dialog for security, the system tool used by tshc. Choose Allow / Allow Once to confirm access on each run, or Always Allow for automatic access. macOS may also ask for your Keychain password, usually your Mac login password. Selecting [ALL] needs only one Keychain read for the whole batch.

If tshc cannot read the saved password, it asks for the KeePass master password in the terminal instead.

To stop using Keychain, set keepass_password.source: prompt in your config and remove the saved password:

tshc keychain delete
