We have a sheet at my company with logins and passwords, shared with all the team, so all the people may enter in the supplier's intranets.
Today, in "shared with", where normally there are 6 to 8 people, I see a person that I don't know and does not belong to my team.
I need to know:
- who of my team made the invitation,
- when it was done, and
- if it has been by manually writing the address in the "share with" box or it has been done by a sharing a link.
How can I "audit" this security issue? I'm the account admin. It's a free account.
