Is it still possible to access my vault with email and master password, if I were to set up Lastpass Authenticator?
Hi@4spetry
Welcome to the LastPass Community.
About your question, once you enable LastPass authenticator, it is required to keep using your username and password and as a second layer of protection after the master password, you need to authenticate your login
Steps are outlined in this support articleUse the LastPass Authenticator app
