Hello @aurielzantua,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having with your account. I have verified the logs for the login attempts on your account and our records show that an incorrect Master Password is being used. Please review your details and try again, you can also try typing your Master Password on a note to make sure it is being entered exactly as intended. If the issue persists, try to reinstall the app.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
