Good habits:

• One person, one account. Never share a single login. If you can't tell who did what, you can't catch a problem.
• Least privilege. Give each person only what their job needs. Not everyone needs the power to move funds.
• Guard the sensitive actions. The stuff that touches money or security settings should sit with the owner, ideally behind an extra check.
• Off-board fast. Someone leaves, their access goes the same day.

The goal isn't distrust — it's that one mistake or one bad actor can't quietly become a big loss. Structure your team's access like it matters, because it does.
