LastPass suffered a network intrusion on Friday and is advising users to change their master password to avoid being hacked. The company says encrypted data was not taken, so, the account passwords stored via Last Pass are safe. Last Pass is also sure the attackers can`t open cryptographically locked user vaults where their plain-text passwords are stored. However, the company advises users who log in to the service from a new device to verify their identities via email or two-factor authentication.”]
