DB Login

Creates a one-click link to login into a PHPMyAdmin instance (or other db management web software) configured for the current site database server.

Warning

Although the login url (admin/db_login) from your Drupal to your DB web interface doesn't mention a password, an http redirection takes place in your browser and this redirection holds all the necessary information (username, password, server url) to login and this redirection will happen in clear text if your connection to Drupal is done accross http instead of https.

Of course if your site is not using SSL, someone could sniff your user/password credentials and hack your install anyways, so the risk is already there - it just makes it a little easier.
