Due to the issues and news from Augustus/December 2022, we all know that our entries which are shown in a LastPass-app are saved as records in a storage. Some fields are encrypted, but not all. URL's and meta-data isn't encrypted. Due to this design, the data is valuable without spending time to decrypt.
In my opinion a whole vault of an user should be stored as 1 encrypted blob in the cloud. When blob(s) are stolen, it's worthless completely, till it's cracked.
