Hi Sarah,
After enable protect a worksheet, it is a password required when we trying to edit that worksheet. If you want to let the user enter the password before they open your workbook, you can follow the steps below to do that:
- Click File>Info>Protect Workbook>Encrypt with Password.
- Type password.
After that, your user can't see the contents before entering the password. Please have a try and share with me your outcome.
Besides, regarding "no option to password protect", I'd like to suggest you post a new thread under Windows category to get dedicated support. Thanks for your understanding.
Thanks,
Neo
