Create new user without password

For a specific use case, I need to add users only by username and email without having to input a password for them.

Right now if i try to leave the password field empty, it displays an error.

How can I create a new user without having to put password without modifying the core? is it possible to remove these fields from the user add form?

UPDATE: why do I need to do this?

referring to my other question here, the google authentication plugin checks (After successful google authentication) if the google email used is found in wordpress, for a given user.

So i just need to create users locally with their usernames and email only. I need to remove the password fields from the form and disable the built in login mechanism (but the latter is related to my other question mentioned above).

Current versions of WP allow creation of a user without creating a password. Just leave password area blank, and verify no password if prompted.

But, best practice might be to create user with a random password, but not tell the user the password. Have them do the ‘lost password’ thing to set up their own password. That’s what I do for my users. I don’t have to tell them a password (sending one via plaintext in an email is not good), and they are responsible for creating a password they can remember.

(Old question without an answer, but guidance is appropriate for current versions and anyone that finds the question.)
