Password will be required if the security setting is enabled for the following features.

Features That Support Security	Conditions for Security
Going to offline mode	When changing to offline mode
Logic monitor	When starting the logic monitor on the display unit
Online Logic Editing	When starting the monitor from GP-Pro EX
Read GP-Viewer EX Data	When connecting GP-Viewer EX to the display unit
Write GP-Viewer EX Data	When writing data from GP-Viewer EX (Touching switch parts, etc.)
View Web Server Contents	When connecting Web Server to the display unit

Save or delete files in a FTP folder	When trying to register/delete files through Web via file transfer

After the changed password is reflected, the new password can be used.

Once you enter the password (log in), you do not need to enter a password afterwards, except as follows:

For View Web Server Contents, Read Web Server Data and Write Web Server Data, once you enter the password on the Server, you are recognized as having logged in. Therefore, you do not have to enter the password.
However, even when you have logged in, authentication is required for security every time you view an HTML page and it is confirmed that the current Web Server log-in data exists in the display unit.
Therefore, if the log-in data has been changed or deleted with the password change feature, an authentication error occurs when viewing an HTML page and a password will be required.
In this case, enter a new password to log in again.
(This occurs in both ID mode and password mode.)

Logic Monitor
A password will be required every time, independent of GP-Pro EX settings.

If the user ID data of the current user has been changed or deleted, the internally held user ID is deleted and the current security level is changed to 0.

If the password required for screen change and the like has been deleted, it becomes impossible to function without the security. However, if the set password has a level equal to or higher than the required level, that password can be used.
