please help!
Hi @samhwlee,
Please be aware that LastPass Customer Care has no knowledge of a user's Master Password and it is not possible for LastPass Customer Care to reset or change a user's Master Password or assist a user with changing/resetting their master password.
If you still cannot recover your Master Password using any of the recovery options here unfortunately the very last and only option available is toReset Your Accountand start over with collecting data (e.g., sites, secure notes, form fill items, creating identities, etc.). This will permanently delete all of your stored encrypted data within your LastPass account, but your account status and some settings will remain untouched. Steps to reset can be found at the bottom of the help article linked above.
