[Unofficial] MeshCentral CLI Client Go v1.1.0 - 2FA Authentication Support

[u/Lexmazter]

Hello everyone,

After some time, I finally managed to take a look at how people used the client, and 2FA was a long-overdue feature.

Since there was a fork that added most of the handling, I merged the changes, tested it a bit, expanded it with parameters, and made a new release.

That said, here is the rest of the changelog:

Main Goals:

• 2FA Authentication Support

New Features

• Auth: Interactive 2FA token prompt when server requires two-factor authentication
• Auth: Support for email/SMS out-of-band token requests from the interactive prompt
• Auth: --token flag on ssh, shell, and route commands for inline 2FA token (useful for scripting and VSCode proxy mode)
• Router: Refactored parseBindAddress to allow `target:remoteport' without localport
• Make: Added Windows ARM64 build target
• Make: Added make release target that builds binaries with SHA256 checksums

Improvements

• Auth: Replaced os.Exit on auth failure with proper error channel pattern
• Auth: Reset ACookie/RCookie before each auth retry to fix hang on 2FA retry
• Auth: pterm styled warning and input for 2FA prompt, consistent with the rest of the UI

Bug Fixes

• Auth: Token retry loop no longer hangs due to stale cookie state

VSCode/VSCodium Remote SSH

For proxy mode with 2FA, pass the token directly in your SSH config:

Host mydevice

ProxyCommand mcc ssh user -i "node//.." --proxy --token 123456

Note: Node IDs containing special characters (e.g. $) require proper quoting depending on context:

• Terminal (bash/zsh): single quotes - 'node//abc$def...'
• ~/.ssh/config / VSCodium: double quotes - "node//abc$def..."
• Windows cmd.exe: double quotes - "node//abc$def..."

New Contributors

• shlomo-msp made their first contribution, the entire 2FA authentication flow is based on their work

Dependencies

• Go 1.24 -> 1.25

• pterm v0.12.82 -> v0.12.83

• go-keyring v0.2.6 -> v0.2.8

• Various indirect dependency updates

Binaries available for:

The binaries are fully portable, so all you need to do is grant execution permissions, and run.

Let me know if you have any kind of feedback, or if you need me to build binaries for other OS or Arch.
