Description

I have a subscription with 5 subdomains set, and use the provided key in the following command. Running the following as sudo succeeds. However, run as the ordinary user:

tunnelto set-auth --key <redacted>

Produces this error report:

name = 'tunnelto'
operating_system = 'unix:Ubuntu'
crate_version = '0.1.12'
explanation = '''

cause = 'Failed to save authentication key file.: Os { code: 13, kind: PermissionDenied, message: "Permission denied" }'
method = 'Panic'

Research direction
The panic occurs at tunnelto/src/config.rs line 86 when trying to save the authentication key file. The error is PermissionDenied, indicating the chosen path is not writable by the user. Investigate the directory determination logic in config.rs; likely it uses a system wide path that requires root. Consider modifying it to use a user specific directory (e.g., $HOME/.config/tunnelto or $HOME/.tunnelto) as shown in similar CLI tools. Review the `set auth` command implementation and test with a non root user.
