Credentials Management

When connecting to network shares, credentials are managed securely:

1. Credentials can be provided via environment variables:

   • OMST_AVR_USERNAME: Username for network share
   • OMST_AVR_PASSWORD: Password for network share

2. Alternatively, you can store credentials in your system's keyring:

   • First-time use will prompt for credentials
   • You'll be asked if you want to save them for future use

3. If neither environment variables nor keyring entries are found, you'll be prompted to enter credentials interactively
