You can continue using the issued client certificate even if you change the user details, such as login name and password. You do not need to issue it again.

However, if you change the status of a user to "Inactive" on the "Users & System Administration" screen, the issued client certificate will become invalid for the user. If this happens, you cannot make the client certificate valid again even if you change the "Status" of the user back to "Active". You need to re-issue the client certificate.

Additionally, you also need to re-issue the client certificate to change the information in the client certificate itself.

For the steps to re-issue the client certificate, refer to the following page.
Configuring Client Certificate Authentication

Note

Even if you change the login name for a user, you may see the previous login name for the user on the issued client certificate when you display the screen to select a client certificate. It is because the login name information at the time of issuing a client certificate is included in the client certificate.
Even if the previous login name is displayed, you can use the client certificate to access and log in to Users & System with a new login name and password.

For example, suppose that you change the login name of a user from "william" to "taylor" after issuing a client certificate. In this case, you can use the client certificate that contains "william" as part of the information to access and log in to Users & System using a login name "taylor" and a password.
