@Otis_, my bad!
Just had a look at the tables at my side and you are right, there are no credentials included in the tables with regard to internal accounts.
You can get (some) information by taking for example the information from the PERSON_INFO table for which the ID is not listed in the PERSON_ID from the LOGIN_INFO table but this will give you no credential information.
I think then the best way to move forward is to use for example the code as suggested by @Kalind_Patel or make use of the (Metacoda tool) as suggested by @PaulHomes
Good luck
