Tech Fix A Breach at LastPass Has Password Lessons for Us All The hacking of the password manager should make us reassess whether to trust companies to store our sensitive data in the cloud.First, it’s important to understand what happened: The company said intruders had gained access to its cloud database and obtained a copy of the data vaults of tens of millions of customers by using credentials and keys stolen from a LastPass employee.That means hackers would then have to crack the encrypted master passwords to get the rest of the passwords in each vault, which would be difficult to do so long as people used a unique, complex master password.Karim Toubba, the chief executive of LastPass, declined to be interviewed but wrote in an emailed statement that the incident demonstrated the strength of the company’s system architecture, which he said kept sensitive vault data encrypted and secured.Though the breach of LastPass may feel damning, password managers in general are a useful tool because they make it more convenient to generate and store complex and unique passwords for our many internet accounts."
