I'm using LastPass password manager extension in Google Chrome. I have to input your MASTER password (LastPass's password) to login and get all the functionality of the manager such as autofill passwords and users in multiple sites, etc.
This login lasts for probably an hour but then after coming back I have to input my master password again because it's logged out. I don't understand, shouldn't LastPass keep a cookie or something (sorry, I'm ignorant) to save the login. Why can LastPass save login for an hour, but not a week? Does some certificate expire? Or is there something wrong with my situation?
Addendum info: If I close Chrome and reopen after 5 seconds, LastPass logins automatically without me entering the password.
