Inquiring if the statement after identified by is the password 'pw12334' to be applied to the account
example
Alter user username identified by pw1234 account unlock.
also inquiring if "identfied by" command alone can replace password without the "replace" command
kinda confused here, since I need to apply the password to apex.xml to make the ords 503 error go away.
the syntax to unlock the user is, the IDENTIFIED BY password is needed becuase if you unlock an account without resetting the password then the password remains expired.
ALTER USER james IDENTIFIED BY Jim123 ACCOUNT UNLOCK;

In ClickHouse, is it possible to GRANT a user for changing his own password but without allowing him to alter his privileges nor the privileges/password of other users?
If I set GRANT ALTER USER TO myuser, I will allow myuser to change the password and the privileges of all the users. And that I don't want.
As I understood the final goal is to avoid compromising/sharing a 'fresh' client password.
I would suggest storing hashed passwords instead of plain text - see for details user settings - user_name/password.
In this case,
user should send to the admin the hashed password
and admin set it up by yourself by using ALTER USER.
I have the following business problem to solve in a big legacy application written in PL/SQL and Oracle Forms 6i:
Not allow users to log in using their database accounts.
The whole application has around 50 users who use their database accounts. The audit department doesn’t allow that users know their database accounts passwords.
Rewriting the application to use a new user rights logic (using a table like USERS, only 1 database user, etc.) is out of the question as it’s too much work.
I thought about the following solution to use the existing database users:
Create a table USERS with usernames and new passwords, and somehow use a proxy user. In a package the application will check if the provided password is in line with the table USERS, and then connect as 1 of the 50 database users – so all application logic and user rights can stay the same.
But there is one problem with this workaround – you can’t use „connect” in a package. So I can’t use it.
begin
IF
p_in_user == USER2 AND p_in_pass == XXX
THEN
EXECUTE IMMEDIATE 'conn USER2/Password123'; -- doesn't work, using a proxy neither
END IF;
END;
Does anyone has any ideas?

You can use encripted passwords.
Oracle allow to use encripted passwords through profile settings.
You can use a function to encript a clear password:
the clear password is given to end user
and on oracle database the user account is created/changed with the encripted password.
The user use his/her clear password to login and during login Oracle conver this to a encripted password for authentication.
Please confirm is this solution is ok, so I can post an example.
I need to debug some user issues which can only be debugged by actually being the user. Is there a way I can impersonate a user without knowing their password? I'd rather not have to reset their password in the DB as that will lose the original one.
Is there a way to make to password invisible in ALTER USER statement ? This statement will run in cmd.
You can force the user to change the password in the next user login by expiring the existing password using sysdba.
ALTER USER username password expire;
Oracle will ask for new password when the username tries to log-in, hence the new password set will be invisible.
But you cannot make the password field invisible in the Alter statement as oracle wont know it is the password field until you enter it in the command line.
If the SQL script is interactive you can use
SQL> ACCEPT pswd CHAR PROMPT 'Password: ' HIDE
This creates a SQL parameter "pswd" which you can use in your ALTER USER statement.
If this is not an option - you might also run the script in SILENT mode to suppress any output from the session.
I have just tried to login to my db via sql developer as system so i can create a new user. It has come with an error that the password has expired.
I have googled a bit but cannot see how to reset the system user password. I guess this is a security issue.
My problem is how can I log in as system if the password has expired? How can I unexpire the password without logging in as System users. I seem to be stuck here in a loop where I cannot reset the password expiration.
Open up cmd.exe and type in SQLPLUS
Enter user-name: SYSTEM
Enter password: the expired password
It will now let you type in a new password for the SYSTEM user
If SQLPLUS is not available, you can also reset an expired password from within SQL Developer:
Save your connection information (if not done already)
Right click on your connection
Click on the “Reset Password” option in the menu, enter old/new password blah blah blah
If someone drops by from a Google search but uses IntelliJ:
You can reset the system password in the connection properties' "Advanced" tab. There you can set the new one as a value for the oracle.jdbc.newPassword key.
