Hello @sciegienna.paulina
Thank you for contacting LastPass Support, my name is Hildaand I'll be assisting you.
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.
Please try the recovery account process using another browser/device you had logged in before, as reference here is the article about what you should consider during the recovery account process https://support.lastpass.com/s/document-item?language=en_US&bundleId=lastpass&topicId=LastPass/recover-master-password.html&_LANG=enus or Revert Master Password Change
If the previous step does not work, you can try to remember your Master Password and try as many times as you wish. Be aware that LastPass won't lock your account, this means you could try Master Password combinations, eventually every 8 failed login attempts, you will see a message saying that "your account has been temporarily suspended" the account will require to wait some minutes for the next attempt.
If after the previous 2 scenarios don't work, then, you will need you to reset your account.
This will delete all the contents within your account, but it will allow you to continue using the same email address with LastPass and set up a new Master Password to log in.
For the reset process, please go to the following article and follow the outlined process.

Thank you,
