If unable to access TAC using default credential (security@company.com/admin), you have forgotten your password.
You can reset it by following these steps:
Establish a connection to the TAC database.
In the TAC database, execute the following statement:
UPDATE 'user' set 'password'=0x21232F297A57A5A743894A0E4A801FC3 where id =<userID>;
Note that `0x21...` corresponds to the encrypted password for "admin". To identify the <userID> associated with the user whose password you wish to update, execute this query: select id, login from user;
Using the new password, log in to Talend Administration Center once again.
