Setting All Account Recovery Options
Once you have created your LastPass account, it is strongly recommended that you set up and configure all account recovery options so that you can regain access to your LastPass vault if your master password is ever forgotten.
If recovery options are not set up and you are unable to recover your master password, you will need to create a brand new LastPass account and re-enter all of your vault data. Learn how to set up account recovery.
Please be aware that LastPass Support has no knowledge of a user's master password. It is not possible for LastPass Support to reset or change a user's master password if it is forgotten.
