 **Note:** You can specify the Apple ID email address and username as arguments when using the tool or by setting them as environment variables (`IPATOOL_EMAIL` and `IPATOOL_PASSWORD`). If you do not specify this information using either of those methods, the tool will prompt for user input in an interactive session. Similarly, you can supply the 2FA code interactively or using the environment variable `IPATOOL_2FA_CODE`.
