+***********************************
+The Change User Password - pgAdmin4
+***********************************
+
+It is a good policy to routinely change your password to protect data, even in what you may consider a 'safe' environment. In the workplace, failure to apply an appropriate password policy could leave you in breach of Data Protection laws.
+
+Please consider the following guidelines when selecting a password:
+
+* Ensure that your password is an adequate length; 6 characters should be the absolute minimum number of characters in the password.
+* Ensure that your password is not open to dictionary attacks. Use a mixture of upper and lower case letters and numerics, and avoid words or names. Consider using the first letter from each word in a phrase that you will remember easily but is an unfamiliar acronym.
+* Ensure that your password is changed regularly; at minimum, change it every ninety days.
+
+The above should be considered a starting point: It is not a comprehensive list and it **will not guarantee security**.
+

+
+Use the *Change Password* dialog to change your password:
+
+* Enter your existing password in the *Current Password* field.
+* Enter the desired password for in the *New Password* field.
+* Re-enter the new password in the *Confirm Password* field.
+
+Click the *Change Password* button to change your password; click *Close* to exit the dialog.

 Pre-compiled and configured installation packages for pgAdmin 4 are available for a number of desktop environments; we recommend using an installer whenever possible.  A standard installation using the pgAdmin installer is a server deployment.
 
-In a Server Deployment, the pgAdmin application is deployed behind a webserver or with the WSGI interface.  
-If you install pgAdmin in server mode, you will be prompted to provide a role name and pgAdmin password when you initially connect to pgAdmin.  The first role registered with pgAdmin will be an administrative user; the administrative role can use the pgAdmin *User Management* dialog to create and manage additional pgAdmin user accounts.  When a user authenticates with pgAdmin, the pgAdmin tree control displays the server definitions associated with that login role.

 In a Desktop Deployment, the pgAdmin application is configured to use the desktop runtime environment to host and display the program on a supported platform. Typically, users will install a pre-built package to run pgAdmin in desktop mode, but a manual desktop deployment can be installed and though it is more difficult to setup, it may be useful for developers interested in understanding how pgAdmin works.
