# Login and Logout

## Login

The login page is the starting page of the web application. Through the *Login* view, it is possible to authenticate with a valid username and password. Furthermore, you can navigate to the *Settings* and *Offline Manual Value Entry* areas. Additionally, the online help can be opened.

### Password Change Request

Depending on the password security rules configured in the Configurator, it may happen that the login fails and thus the user must renew or change their password. The following error messages may appear:

* 3001 - The user account password has expired!
* 3003 - The user account password must be renewed!
* 3004 - Error during password verification!

In such a case, a modal window automatically opens where you can then enter the new password. Now enter your current password and then twice your new password, and then click *Save & Login*.

If the new password does **not** fully comply with the password security rules configured in the Configurator, a corresponding *password strength* indicator will be displayed. Depending on the password strength, the user is forced to use a certain number of digits, special characters and/or a mix of uppercase and lowercase letters in their password.

The user may also see information displayed when logging in that the user's password will soon expire. In this case, the user can decide for themselves whether to change the password now or ignore the info message. When ignoring the message, the user is navigated further. Otherwise, the above-mentioned modal window for changing the password opens.

## Logout

A logout is possible at any time in the menu under the entry *Logout*. This prevents unauthorized users from gaining access to the JUNE5 system.
