Can I programmatically login a user without a password?

Question:
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?

Answer:
The following code does the job for automatic login, without any password!

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

// Automatic login // $username = "Admin"; $user = get_user_by('login', $username );   // Redirect URL // if ( !is_wp_error( $user ) ) {     wp_clear_auth_cookie();     wp_set_current_user ( $user->ID );     wp_set_auth_cookie  ( $user->ID );       $redirect_to = user_admin_url();     wp_safe_redirect( $redirect_to );     exit(); }
