Hi Enpass:

Is it possible that a business adminstrator could somehow intercept、read out their member's password? 

Sincerely!

For example,  force to locate my vault in theire computer,  move/copy my vault to their computer without my aware.

Hi @turbowolf

Welcome to the Enpass Forums.

I would like to share that none of the data or encryption keys is stored on our server. Until the admin knows your master password, any access to the encrypted vault file by other means is of no use.

That's great!
