- Login
- Start a tool: Search and Dictionary Search are available without login.

If you click "Login"', a new window opens. Use your user name and password you received via e-mail or choose the login via DFN-AAI (= authentication and authorization infrastructure of the German National Research and Education Network). If you have forgotten your password, use the button "Forgot Password?'' further down. After your first login you are asked to complete your user attributes and to accept the "TextGrid Terms of Use". If you set the option "Searchable'', other TextGrid users will find you by your name, institution or e-mail-address. The fields with an * are mandatory. You can change your attributes at any time via "Help > Authentication'' in the menu bar of the Lab.
