Overall we try not to. Make it so everyone has their own login/password so you can control access and limit liability now. The problem with shared credentials is you do not know who did what and in the end that can bite you. Also, it can become a nightmare when you need to update a password to keep things secure and finding out who needs it and who has it etc.
And almost always, when you share a password the pain of updating it becomes so great you stop and then everything becomes even less secure.
If you must do it for some reason, I'd suggest trying an app like 1password or similar and sharing the vault between computers.
