Second job of the day done: exported all the info I needed from lastpass and set it up in a new password manager, deleted the CSV. Now to update all the passwords. Bozhe moi, when Last Pass fucked up they did it properly.
@BethanyBlack Which one did you go with if you don't mind me asking?
@afewbugs bitwarden for now. Seemed to be the best rated open source one.
