Sometimes you maybe foget the password of Magento Admin, don’t worry now.I intro you a way to reset magento admin password now.
It seems like the password must be typed and not copy/paste at least on the install part.
The default login is : admin The default password is : 123123
If you are having troubles and want to reset it to a different password, just run:
SELECT * FROM admin_user;
Then, find the username you want to modify in the listing provided – ‘admin’ in this example. Then, to update the password, type:
UPDATE admin_user SET password=CONCAT(MD5('qXpassword'), ':qX') WHERE username='admin';
‘qX’ would be changed to whatever you want it to be and same goes for ‘password’
You can also do this in phpMyAdmin, find the admin_user field and choose MD5 when updating password.
Also you can change the other password,but you must know the MD5 of password.
