I suggest enabling an integration with AD for ssh authentication to have a better control and audit of administrators and not share the tideway password among multiple persons.
This is a security breach and I believe in the future security teams will not allow multiple users to use the same account for administration activities.
I would see a high level implementation this way:
-enable AD integration
-disable remote logins for all local accounts, including tideway
-grant sudo rights towards tideway for LDAP users.
