Can I programmatically login a user without a password?

I’m manually creating users programmatically, and I want to sign in the newly created user. WP makes it easy to access the hashed password, but not the plaintext version. Is there a way to use wp_signon() without the plaintext password?

I found one person who claims to have done this here, but it didn’t work for me.

THANKS!

wp_set_auth_cookie() will log a user in without having to know their password.
