I agree about not wanting to have passwords in command line users' history, but I think supporting an optional password flag would be the simplest route. I'm thinking of the mysql client as an example, where you can supply -p without anything else and it'll interactively prompt for a password, or accept a password along with the flag if you want.

One prerequisite I see for this is changing the authentication process. Currently the write.as cli asks for input in the form of the password, after you feed it a username. I'm not sure
