New User’s Password – How To Let Them Know?

Hi, just a quick question,

If a user sets up an account with the UM registration form, they choose a password. However, if the user is added from the backend by me, they receive a welcome/activation email but no password. And if they need to reset it, they need the current one to do this.

I can manually email them the password, but wanted to know if there is a simpler option?
