LastPass Enterprise is a version of LastPass that is designed for teams. Everyone should have some sort of password management to prevent you from using the same one or two passwords on every site across the entire Internet. If you aren’t, there is a free version of LastPass and other similar products to help you out with this problem.
I use the enterprise version with my team to sync sensitive passwords to things that we only have one account to. Now, we can have 30 digit passwords that make no sense AND regularly change the password. Then, when we do this, LastPass automatically remembers the change AND syncs it to all of our team members.
This has totally removed the need to send emails out with passwords and keep random plain text files of sensitive information.
I hope this is useful to you. Please send a reply on Twitter to me @thejedi.
