By the house rules, tools on the toolserver must not ask for passwords for users on Wikimedia projects.
However, sometimes it is neccessary for a tool to verify the identity of a user to perform some operation on such a project.
Here, you can create a new account, with a new password, and then verify it against a Wikimedia project by performing a specific edit.
You can then identify yourself in toolserver tools by giving this new account.
Step 1: Enter your existing data
Note to tool authors : you can check if a user is verified like this:
http://tools.wikimedia.de/~magnus/tusc.php?check=1&botmode=1&user=USERNAME&language=LANGUAGE&project=PROJECT&password=TUSC_PASSWORD
This will return '1' if the password is correct and the user is verified, and '0' otherwise
Of course, you should use POST requests, otherwise the passwords will show up in the toolerver logs...
