Domino has no control on how browsers store username/passwords in the local cache of the browser.
Using customise login page created in inotes.nsf and this is set in Domcfg.nsf. Both the Username & password fields are set with enable encryption for this field option in field properties. Also have SHA2 certificate for application but are still getting password in plain text at application layer & while sending it to server and with memory reading tool such as Winhex. It is getting in plain text through
browsers developer option too.
