I see no issue.

I don't know the technical answer, but the common sense answer is don't do it.

If your password is hacked/discovered, it will give the hacker access to everything you own.

Bad choice, in my opinion.

Sorry, I'm not used to your system. I meant for my reply to go to the original questioner.

Maybe with practice, I will improve.
