Separate table for username and password with other fields

Is there anyway to make the authentication table with 2 separate table
currently my authentication table has following fields
username,password,userlevel,higherlevel,profile

I would like to separate the above table into 2 tables as
1)authentication // mssql database “DB”
a)username → Login username
b)password → Login password

2)authentication2 // mysql database “LinkDB”
a)userlevel → User Level
b)higherlevel → Parents Level
c)profile → Profile Field

NOTE :: I can not use the view table as the above 2 table will be store in 2 different database.
As I am working to a old database of a company I have only readonly permission on “DB”

I don’t think so. You should create a new table in your main database to be used as “users” table.
