What I have done:
I have added multiple google accounts to my device. Also did set screen pattern lock and pin as fallback. Tried to give wrong pattern and selected unlocking by google account, I could use any active google account and it will remove both pattern and pin.
How I want it to behave:
I am lookin for some way to restrict unlocking/pin reset to individual selected google account while retaining keep/drive/mail/contacts/calendar etc, synchronization, is that even possible?
