Not able to connect after changing the password using ALTER VALUES clause

Question

Hi,
Just now John explained about VALUES clause in below thread.
Expired Status
I created a new account called SURI and tried to use the user account HR's password using VALUES clause. I was able to alter the password but not able to connect SURI with hr password.
Please see the version details below. And the SQL statements which I have tried.

SuriYou can only do it for the same user, as the password is a hashed value that includes the username as part of the hashing (It's either the username or some internal object id or something). So using the hashed value against another user won't work.
