How do I revert to my previous master password?
Reverting your master password means that you are resetting it back to your previous master password, and in doing so, your LastPass vault will be restored exactly the way it was since the last master password change. This may result in data loss (i.e., any new items updated/added since the change will not be recovered).
Suppose you changed your master password on April 1, 2021, but on April 15, 2021, you have forgotten your master password and you need to revert back to the April 1 master password. If you do this, any changes you made to your vault since April 1, 2021 are lost; your vault is restored to exactly how it looked on April 1, 2021 right before the master password change.
