How do you handle brute force / dictionary attacks for my LastPass account?
LastPass stores a record of each login failure on a global and per IP bases.
If attempts passes a threshold of failures we start doing lockouts. We also have a global lockout threshold if someone distributed an attack against your account. This does not impact you logging into your locally-cached copy of your data and we notify your email address if this happens.
