    This has been a concern of mine for some time. In all honestly my concern has not over powered my desire of simplicity for time management. My questions is using snipits, do we use 3 party software or use what the operating system provides? OS didn’t seem to focus on that so it’s limited by using only the OS. Suggestions and ?are welcomed ??

      I'm not totally sure what you're asking -- do you want to know if it's better to use your browser's built-in password/autofill manager or a third-party one like LastPass or Dashlane?

    This is an interesting one. I'm quite an impatient guy, so anything that cuts down some precious time is fine with me... except, as you say, it *is* a security concern. Even DOB and address information can be of use to cybercriminals. Convenience over security or vice versa? It's tough. I personally think you're okay as long as your don't save passwords or anything mental like that.
