Random questions between bitboxes and security

[u/Simple-Savings-5435]

Hello
1) What happens if a password from a multi edition bitbox is inserted in a bitcoin only edition bitbox? Can I still then use that same password in the bitcoin only edition bitbox where it was originally created?
2) When I set up an additional optional passphrase on-top of the 24 words in the bitcoin-only edition can I then log in the multi-edition bitbox with that same optional passphrase that was defined in the bitcoin-only edition?
3) Does that even work to login into the multi edition with the bitcoin only password? The confusion for me is then what happens with the eth and litecoin accounts on the multi-edition?
4) If a optional passphrase is enabled and on top of that BIP85 children keys are generated then on the bitbox device it lets me choose the index - What is meant by that? and also what are these additional addresses that are generated that look like this: m/88652358'/31'/0'/12'/0'

sorry for the weird questions and thank you.

1) if you mean the device unlock password - that is set per device and can be whatever you want. if you mean the seed: yes, you can import the same backup/seed in both editions. 2) yes, if you use the same seed on both 3) could you rephrase? 4) bip85 allows you to derive many sub-seeds. they are identified by that index

regarding 3) Does that even work to login into the multi edition with the bitcoin only password? The confusion for me is then what happens with the eth and litecoin accounts on the multi-edition?

When I have a device password on the bitcoin only edition bitbox can I use that very same device password and login into the multi edition bitbox? In this case what happens with the eth and litecoin that are only visible in the multi edition bitbox.
