Using frontend web technologies for keeping passwords safe is not the best idea. Lastpass has "restricted" password copy functionality, if passwords were shared. But it actually loads password to input field with type set to password. Open up inspect tools, change input field type to text and you have a password in plain text, you can easily copy.
