A: Assuming you are not using external user authentication – the password you seek is logded firmly in your database. If you have access to CPanel, you can retreive it. From Cpanel, goto MySQL Databases, then PHPMyAdmin. Select your database (usually somthing_tiki) scroll the list of tables way down to users_users table in the ti the password will be in there.
These are not encrypted in most dbs.

In case your tiki encrypts password you can use the following SQL command: (cut and paste the following exactly into the SQL window in PHPMyAdmin.

UPDATE `users_users` SET `password`=’admin’, `hash`= md5(‘adminadmin’) WHERE
`login`=’admin’;

this will set the password to “admin” again. You are saved.
