To increase the security of your master password, LastPass utilizes a stronger-than-typical version of Password-Based Key Derivation Function (PBKDF2) at a minimum of 100,100 rounds. You can change your password iterations value to suit your needs and/or for troubleshooting.

1. Log in to LastPass and access your vault by doing either of the following:
   • In your web browser toolbar, click the LastPass icon and select Vault or Open My Vault.
   • Go to https://lastpass.com/?ac=1 and log in with your email address and master password.
2. Select Account Settings in the left navigation.
3. Click Show Advanced Settings.
4. Within the "Security" section, for the Password Iterations field, enter your desired number of rounds (our minimum recommendation is 100100 rounds).
   Important: Numbers only. Do not enter a comma, period, space, or any other punctuation.
5. Click Update.
6. When prompted, enter your master password and click Confirm.

   Result: Your vault data becomes re-encrypted, and you are automatically logged out of LastPass.

7. Log back in to your LastPass account, and the changes will take effect.
