Hi, please check the following possible solutions.
1. Oh okay, for Chromebook, you use Excel Web Version. I have looked but couldn't find a way to put a password on an Excel file either via Excel for iOS or Excel for Web - Unfortunately I don't have an Android phone so couldn't check that.

However, a possible solution can be - if you create a couple blank Excel files on a computer using the Excel app and password protect them with different passwords, you can then duplicate those files whenever you want to create a new password protected file. Both Excel Web Version and Excel for iPhone allow to open password protected files and I am pretty sure that Android would too.
2. There isn't a way to save the Excel file to an external storage on Excel Web Version but Excel for Android does. Please check out this link: https://support.microsoft.com/help/4c584089-1909-4bb1-91f3-8709c705be48
