The attack speed of 15,500 passwords per second using a GeForce 2070 GPU is about average, offering reasonable protection of the password database if the user sets a long, complex master password that is not based on combinations of dictionary words. Attacking the database directly would result in the following speeds: The LastPass database we obtained from a Windows computer was protected with 100,100 hash iterations. The database is secured with a password, which, in turn, is used to generate the encryption key after going through some 5,000 to about 100,000 rounds of hashing depending on the platform.įor security reasons, desktop platforms offer the best protection. Technically speaking, LastPass keeps all passwords along with other authentication credentials in a SQLite database. Similar to other password managers, LastPass may use different protection settings to protect password vaults on different platforms, desktop apps carrying the strongest protection and Android app using the weakest protection.

Due to the sensitive nature of the information stored in the password vault, LastPass applies strong encryption and uses multiple rounds of hashing to slow down potential brute-force attacks. The database can be encrypted with a master password. LastPass collects and stores user’s passwords in a local database. More interestingly, LastPass can be installed on multiple platforms as a cross-platform browser extension in many popular browsers. LastPass offers desktop apps for Windows and macOS, as well as mobile apps for iOS and Android. Similar to other password managers, LastPass is designed to store, manage and synchronize passwords, which supposedly helps using complex, unique and non-reusable passwords for the many online accounts without having to memorize all of them. Introduced by Marvasol Inc (acquired by LogMeIn) in 2008, LastPass is one of the four most popular password managers. In this article, we’ll demonstrate how to unlock LastPass password vault instantly without running a length attack.
Using encryption and thousands of hash iterations, the protection is made to slow down access to the encrypted vault that contains all of the user’s stored passwords. Password managers such as LastPass are designed from the ground up to withstand brute-force attacks on the password database.
