About Oracle Default user Name System password incorrect login not on solution

If you can log in to any of the users, you can use the method to know which users are currently available.
SELECT distinct owner from All_objects to view the current user.

If you don't set a password when you install it,

Oracle has three default user names and Passwords
1. User name: sys password: change_on_install
2. User name: System Password: Manager
3. User name: Scott Password: Tiger

Or maybe you set a password that complies with the Oracle check rule when you install it, but the password is incorrect when you log in, which may be the reason for the character set you installed at the time of installation.

Solution:

1. You can change other account password after login using SYSDBA account
