Accidentally merged iCloud : need help with Notes

[u/Apprehensive_Cry_762]

This could really be in the TIFU sub. Sigh.

Had to sign in to my daughter’s iCloud on my device to help with something (yes, please no admonishing. I realize the error now.). My data including passwords and photos (as far as I know so far) got merged so when we signed her out she ended up with my photos and passwords on her device.

I have some notes that are locked on my phone. I use face id to unlock them. If they show up on her phone, can she unlock them?

If someone has previous experience with this I would greatly appreciate your help.
