I am a LastPass admin for our company and my Admin Console provides me with a list of who are reusing their master password. I've discussed this with the users who's name appear in this list and they deny having reused their password.
At times LastPass (because it doesn't always notify) tries to identify which site it is being reused. Several times, users showed me that the passwords are not identical so I question how accurate is this list. I would like to understand how the system determine how someone is reusing their master password and is the list trustworthy.
