Quick Start
puttyalt.msi [user@]host[:port]
Download. Double-click. Connect. That's it.
Windows SmartScreen
First launch may show a SmartScreen warning — this is normal for unsigned open-source software.
To bypass:
- Click "More info"
- Click "Run anyway"
Or run in PowerShell:
This happens because the EXE is not code-signed with a paid certificate. The software is fully open-source — inspect the code yourself.
