Thank you for reaching out to LastPass support, my name is Hilda and I will be assisting you with the issue you're experiencing.
We understand that you cannot log in to your LastPass account. As of our records, we received failed login attempts due to incorrect master password.
Try using another entry or go ahead and follow the process on this article, make sure to use all the options available https://support.lastpass.com/s/document-item?language=en_US&bundleId=lastpass&topicId=LastPass/recover-master-password.html&_LANG=enus
If recovery doesn't work in this case, we will need you to reset your account.
This will remove everything from your account, but it will allow you to continue using the same email address with LastPass.
