What is the default Joomla 2.5 user edit profile url?

The default url for Joomla 2.5 to access the user edit profile page form without creating a menu link is:

index.php?option=com_users&view=profile&layout=edit

Just add that string after yourwebsitename.com

For example:
http://www.yourwebsitename.com/index.php?option=com_users&view=profile&layout=edit
