LastPass notified customers today that they are now required to use complex master passwords with a minimum of 12 characters to increase their accounts' security.

LastPass will finally enforce a 12-character minimum master password An overdue safety upgrade after a major security meltdown.

A 6-character password can now be breached in just seconds using brute force techniques in which a computer tries every possible combination of characters to work out the correct sequence.

LastPass is enforcing longer 12-character master password for all users. The password manager will also cross-check passwords on the dark web.

The research team tested more than 1,400 passwords containing 16 or more characters against a grammar-aware password-cracking algorithm and found that grammatical structure can undermine security.

According to the Hive Systems Password Table, the more your password has, the longer it takes for a hacker to figure it out.

An 8-character password made up of just numbers can be cracked instantly and lowercase letters in 3 weeks. And remember, that’s random lowercase letters, not a word.
