Sharing keychain
Can I share my keychain with other members of my Apple family?
MacBook Pro 15″, macOS 10.15
Question marked as
No keychain folder from user library and its password can't be shared when family sharing account is activated see the article https://support.apple.com/en-us/HT204976
This way your family can share purchases, an Apple Music family plan, iCloud storage, photos, and more without sharing personal information like email, text messages, or passwords .
