Recover admin password and email Odoo server

Months ago, I installed an Odoo server and it worked perfectly !

Problem is that I forgot the identification (email/pass) for the admin, wich is real bad. After uninstalling the server and reinstalling it I found out that the database was not wiped. So it didn't change at all !

Please, can anyone help me finding the admin's email and password ?

I'm not very familiar with progresql but res_users displays empty passwords:

Where is the master password in Odoo?

The "master password" is named "admin_passwd" in the config file (usually, "odoo. conf".)

What is the default password for Odoo?

All is working fine, but with the default user & password is admin:admin.

You may change admin password using progresql from the terminal. You just need to do like these

odoo@odedra:~$ psql testing_db
psql (9.1.14)
Type "help" for help.

testing_db=# UPDATE res_users SET password='new_password' WHERE login = 'admin';
UPDATE 1

where testing_db is database name.

Now login with new password and change user details whatever you want.
