Two-Factor Authentication¶
Enter verification codes when SSH servers require additional authentication.
How It Works¶
- StormTunnel establishes the initial connection
- The server requests a verification code
- A secure input dialog appears
- Enter your code and click Submit
- Connection completes if the code is valid
Entering Codes¶
- Check your authenticator app (or wait for SMS/email)
- Enter the code in the input field
- Click Submit or press Enter
Cancel with Cancel or Esc.
Code Expiration
Most TOTP codes expire in 30 seconds. Enter promptly.
Supported Methods¶
| Method | Description |
|---|---|
| TOTP | Time-based codes from authenticator apps (Google Authenticator, Authy, 1Password) |
| SMS | Codes sent via text message |
| Codes sent to your email | |
| Hardware tokens | YubiKey and similar devices |
StormTunnel displays whatever prompt your server sends, so custom 2FA methods work too.
Security¶
- Masked input -- Code characters are hidden during entry
- No storage -- Codes are never saved to disk
- Session-specific -- Each code applies only to the current connection
