No. The dba_users password column stores a hash value of the concatenation USERNAME || PASSWORD.

If the two usernames are different, user2 will most likely not have any password at all. If one is a prefix of the other, the passwords will have the reverse relation. If the usernames are the same, then the passwords will be identical.

If I have two users existing in two separate databases ( and these users have the same value in the password column of the dba_users view, does this mean that they have the same passwords?

In other words. if I enter the following command:

alter user USER1 identified by values 'XXXXXXX'

where XXXXXX = select password from dba_users where username = 'USER2'

will the USER1 and USER2 have the same passwords?

thank you
