Although not as convenient as a browser entering password crypt, if data could be retrieved from the “container”, interactively, one could put an encrypting program in the container, and be as sure as comodo’s protection is sure, that it could not reach out and share the account/passwords, but data there could be copy/pasted to use in a browser, and if the edited data could be taken out, a high level of security would be available.
Combined with dropbox, this could give very good ransomware protection. (If hijacked, can plan to go back to bare metal) Product keys and login/passwords could be kept there. Somehow buying software that I have not written and compiled and just running it with this data does not feel very secure.
